Reviews

ajayjudge I liked the first 6 or 7 seasons but the laugh tracks do get annoying but those first seven seasons do have a lot of classic episodes like the precious fragmentation or the staircase implementation or even the Russian rocket reaction. The show is a must watch especially for fans of pop culture and movies. Season 8 9 and 10 aren't the best but the end of season 10 is great no spoilers but it has a good ending. I still don't really like season 11 but that's my opinion you see the show you see it. The show is great quick breezy watch fun for the whole family and a must watch that's funny has problems but still great and I love it.

tombraider-48099 This show is hilarious and there are alot of episodes i love and they are really funny. I love Sheldon in this show he makes me laugh. I also love penny when she makes the most funny faces. An old friend of mine told my brother about it and he told me so i started watching it. I don't really care the the new seasons cause they are not funny at all just like the reruns of the episodes from the earlier seasons. The Big Bang Theory is my favorite show!

alley117 Apparently only negative people write reviews...not sure what everybody it talking about because this show makes me laugh just as hard now as it did in the first seasons. It got so much better with the addition of Amy and Bernadette who mellowed out the male characters and made them feel more realistic and believable. The characters have developed so well throughout 12 seasons, the show is hilarious with a lot of scientific and nerd humor thrown in!

Cleavant Derricks What a coincidence... I just wrote the 300th user review on IMDb for "Two and a Half Men" and now I find I am writing review #500 for "The Big Bang Theory!" I feel very special and truly honored. Thank you IMDb and fellow users for making this possible...Now for my review...BE WARNED. "The Big Bang Theory" is NOT "Sliders"... It has in fact very little to do with "Sliders".I had high hopes because the characters in this show practice science, including some very advanced stuff. I assumed that, since Jerry O'Connell was merely a high school student working on his own, obviously several college geniuses, who are experts in different scientific fields, must be able to unlock the mysteries of inter-dimensional travel. But NO.Shame on the producers and writers of this show for making viewers believe it will be a great show like Sliders, only to have us find out when watching that it has zero sliding at all.Sheldon is a huge wimp I can't respect at all. He's lucky he doesn't have to slide from one dimension to the next, where he is relied upon to solve an entire world's problems in a short period of time - because he would fold under the pressure, unlike Mr. O'Connell.Leonard is also nothing compared to Professor Arturo either. He's just a nerd. Professor Arturo can FIGHT ROBOTS single handed while Leonard has trouble even building ONE robot over a period of years. He even has trouble just talking to girls. The Professor ruled an entire planet of women, with no sweat!As for the other two nerds, they are nothing compared to the gorgeous Wade and The Crying Man. Seriously, do I even need to get into that one?Also the characters in this show are thinly veiled racial and sexual stereotypes, and the jokes are predictable and written by hacks... so there's that too.I give this show a 2, because it fails at being Sliders but at least there's some physics in it, which means there is at least the potential for future sliding...
