The Big Bang Theory remains CBS’ most popular program, and while it’s still one of the better comedies on television, season seven shows some slight signs of fatigue.
The interaction among all the lead characters, especially when they’re all onscreen together, remains witty and sharp, such as the episode where Raj conducts a scavenger hunt and the couples pair-off with someone besides their significant other. Another standout episode features Bob Newhart returning as the retired (and somewhat bitter) Professor Proton, once again stealing every scene he’s in. But topping Newhart is James Earl Jones, playing himself as he paints the town red with Sheldon after the boys are unable to secure tickets for the local Comic-Con. Speaking of Sheldon, this is the season where he finally kisses Amy.
On the other hand, while these characters mostly remain pretty amusing, season seven is essentially more of the same, which may be good or bad. Sure, their geeky-as-ever personas are still charming and funny, but there are a few episodes which fall flat, especially those where Sheldon’s personality is exaggerated to the point he’s more obnoxious and unlikable than endearingly clueless. On the other hand, we’re spared any jumping-the-shark storylines (like when Howard became an astronaut in season six). But at this point, especially in later episodes, one can see the light at the end of the tunnel, when everything has played itself out, and continuing the show any further would wear out it's welcome.
One can only hope the powers-that-be will realize when that moment arrives in order to end the series on a high note.
