he is still funny and kind but shows it lest.

Deep down he's still the same, but he's acting a little bit more heartless lately....

I know want you mean.

i like this new dark vibe he's got going on.

I agree with Happy_Fantasy, he's got a new "dark vibe" that is nice
And maybe he is a bit more confident, because of his new abilities... but he's still Chuck =)

the show has lost it's "dorkiness" which was so sweet and wonderful. I miss the old Chuck. I think the producers and writers sold out for the ratings because they were afraid the show would be pulled completely ... I can't watch it anymore. I used to watch every week. Too bad.

I agree with Musiolette

His change is natural. His entire life changed, he has an intersect in his brain, he can do stuff he never thought he would, etc. It's natural, he's a human being, everyone changes over time, especially considering the things he has gone through for the last few years of his life. But I don't think it's a bad change, like you said he has a dark vibe, a bit more confidence, etc...but it's not a bad thing.

What? No of course not, it has become more exciting to me in time! :)
