Watch The Big Bang Theory Online at CouchTuner . This fun, well-written series features an endearing cast who provide viewers with lots of humorous moments. Leonard, Sheldon, and their friends fully embrace their genius and recognize their social shortcomings. They also understand the value of friendship, loyalty, and staying true to themselves.Still, while the show is definitely funny, its storylines about camaraderie and romance aren’t exactly original. It also promotes all of the expected clichés about people in the sciences — they have a passion for sci-fi characters and can’t sell a pick-up line to save their lives, etc. — and, in Penny, it sometimes puts forward the stereotypical “dumb blonde” image. But in the end, this show is about a group of nice guys basically having fun and looking for love.
