Will They or Won't They...goes too far.
Let me start out by saying this show had tremendous potential. Like many shows, it starts out extremely well, and looks like it's only going to get better from there...
But then, like many shows, it Jumps the Shark. It's hard to say exactly where this happens, but I think it's most likely at the end of Season Two.
For those concerned, spoilers;
For the first two seasons, Chuck and Sarah dance around their relationship, until finally, at the end of season 2, Sarah is willing to give up absolutely everything, just to be with Chuck.
Then, following the explosive climax of season 2, we suddenly have a MASSIVE return to status quo. Basically all the progress that has been made over the last two seasons is reset, and we have to watch basically the same things happen AGAIN, except this time with the stakes higher than ever...and even worse, with the loss of one of the series' best qualities; its comedy.
Just let me make this clear; for the first season, chuck is a comedy with dramatic leanings. For the second season it's a straight dramedy, but still had moments even more hilarious than in season 1. But in season three? Dramatic events start happening just for the sake of being dramatic. The characters never LAUGH anymore. There are tears, but very rarely are they of happiness.
And the series just goes downhill from there. You can't just take away one of the primary elements of the series and hope to have it survive.
So yeah; watch it to the end of season 2, then imagine that they saved the day, beat FULCRUM
, and lived happily ever after. You'll be infinitely more satisfied than if you watched it for real.
