The fifth season of the American sitcom The Big Bang Theory was originally aired on CBS
from September 22, 2011 to May 10, 2012 over 24 episodes.
Cast
Dr. Leonard Hofstadter, portrayed by Johnny Galecki, is an experimental physicist with
an IQ of 173 who received his Ph.D when he was 24 years old. He shares an apartment with
colleague and friend, Sheldon Cooper. He and Penny dated at one point during the series,
but they broke up during season 3. They start dating again in season 5, though their relationship
is rocky. Dr. Sheldon Cooper, portrayed by Jim Parsons,
is a theoretical physicist. Originally from East Texas, he was a child prodigy, starting
college at the age of 11, right after completing the fifth grade. He received the Stevenson
award when 14 and received his Ph.D when he was 16. He has an IQ of 187 and exhibits a
strict adherence to routine; a lack of understanding of irony, sarcasm, and humor; and a complete
lack of humility or basic empathy. He is dating Amy Farrah Fowler, when he asked her to be
his girlfriend. Penny, portrayed by Kaley Cuoco, is a waitress
who lives across the hall from Sheldon and Leonard. She has aspirations to an acting
career, but has not been particularly successful thus far, only boasting a few small roles
as well as a part in a hemorrhoid commercial. She and Leonard dated during season 3 and
broke up. In the finale episode of Season 4, she was thought to have slept with Raj
after drinking, but Raj revealed to her they did not. During season 5, Penny begins to
date Leonard again though their relationship is rocky. Her last name has never been revealed.
Howard Wolowitz, portrayed by Simon Helberg, is an aerospace engineer. He is Jewish, and
lives with his mother. Unlike Sheldon, Leonard, and Raj, Howard lacks a Ph.D. He defends this
by pointing out that he has a master's degree in Engineering from MIT and the equipment
he designs is actually built and launched into space, unlike the purely abstract work
of his friends. He provides outrageous pick-up lines and fancies himself a ladies man with
suitably unimpressed reactions from Penny. Though he finds that he has limited success
with other women at first, he begins dating Bernadette in season 3, but they break up.
They get back together in the Season 4 episode "The Hot Troll Deviation", become engaged
in the episode "The Herb Garden Germination" and are married in the last episode of this
season. At the end of the season, he goes on a Russian Soyuz rocket to the International
Space Station. Dr. Rajesh "Raj" Koothrappali, portrayed by
Kunal Nayyar, is an astrophysicist originally from New Delhi, India. Known commonly as "Raj",
he works alongside Sheldon exploring the string theory implications of gamma rays from dark
matter annihilations. He is very shy around women and is physically unable to talk to
them unless he drinks alcohol. His sister, Priya, dates Leonard in season 4 and part
of season 5. Dr. Amy Farrah Fowler, portrayed by Mayim
Bialik, is a neurobiologist. Raj and Howard meet her on an online dating site using a
fake account for Sheldon. She is very similar to Sheldon, except that she is more open to
social interaction and thus more susceptible to conventional behavior. She becomes close
friends with Sheldon, prompting regular assertions from him that she is a girl and is his friend,
but she is not his girlfriend. She finally became his girlfriend when Sheldon decides
to change the course of their relationship after he becomes jealous when Amy goes out
on a date with comic book store owner Stuart Bloom. Amy also forms a quirky friendship
with Penny, whom Amy frequently refers to as her "bestie" and becomes Bernadette's Maid
of Honor at her and Howard's wedding. Dr. Bernadette Rostenkowski, portrayed by
Melissa Rauch, is a microbiologist. Bernadette is introduced to Howard by Penny while the
two were working together at the Cheesecake Factory. At first she and Howard do not get
along, as they appear to have nothing in common. When they find out that they both have overbearing
mothers, however, they feel a connection. She was upgraded to main cast status in the
episode "The Hot Troll Deviation", in which she and Howard revisit their previously unsuccessful
relationship. She and Howard get engaged, and much comical fodder is created through
similarities between Bernadette and Mrs. Wolowitz. She marries Howard at the end of this season.
Production Several high-profile celebrities appear in
the season. In "The Transporter Malfunction", actor Leonard Nimoy appears as a voice actor,
playing an action-figure Spock that Sheldon imagines talking to him. In the following
episode, "The Hawking Excitation", cosmologist Stephen Hawking appears as a guest star. Astronaut
Mike Massimino appears in "The Friendship Contraction" and "The Countdown Reflection".
Stephen Hawking went on to appear in the season 6 episode "The Extract Obliteration" and the
season 7 episode "The Relationship Diremption". Mike Massimino later appeared in the season
6 episodes "The Decoupling Fluctuation" and "The Re-Entry Minimization".
The season finale depicts Howard Wolowitz traveling to the International Space Station
on board a Soyuz rocket. Thanks to technical consulting from Astronaut Mike Massimino,
who also plays himself on the show, the production crew was able to put together sets that realistically
depicts the Soyuz capsule and the ISS. The Soyuz capsule was constructed based on photos
from NASA, the Kansas Cosmosphere for dimensions, and scavenged parts from an aerospace junkyard
in Los Angeles. Release
Critical reception On Rotten Tomatoes, 100% of seven critics
gave the season a positive review. Oliver Sava of The A.V. Club gave the season
a B+ rating. He described Raj as the "weak link of the show" as he has not "[evolved]
like the rest of the cast" and is "trapped in season one mode". Sava gave high ratings
to episodes where Raj did not feature prominently, such as "The Pulled Groin Extrapolation" or
"The Russian Rocket Reaction" and described "The Wiggly Finger Catalyst" as "one of the
series' worst", giving it a D+ rating. Sava's favorite relationship on the series is between
Amy and Penny. Jenna Busch of IGN disliked the previous season
but said that season 5 "is far more balanced"; Busch gave season 5 episodes ratings between
5.5 and 9, with an average rating of 8.0. She also noted that the show has "matured"
by included other women in the main cast. Tom Gliatto from People gave the season 3
out of 4 stars, stating that it is "bright and obvious as a cartoon, yet written with
a clean, precise patter of jokes". Awards
