I think this is going to be the last time I review The Big Bang Theory on a regular basis. It's a lot easier to watch the show without thinking too much. Take "The Russian Rocket Reaction, " a decent episode by TBBT standards. Howard and Bernadette dealing with their problems together and Sheldon vs. Wil Weaton actually getting a resolution--all more than what's usually in an episode.
But while those things happens, I can't help but notice how unlikable the characters are half the time. Howard's yelling mother has been completely oversaturated at this point, and the yelling, by Howard, his mother, or Bernadette, is quite off-putting. Finally, there's Sheldon, whose supposed intelligence is overshadowed by the fact that he's stupid at times, like when Leonard is haggling. If he's going to be so annoying and arrogant about everything, he should also back it up by never being dumb.
