It’s good to hear the view from another perspective. I get what you’re saying, I guess I’ve been looking at it from the point of view that the original goal of the character Chuck was to get the Intersect out of his head, and for some reason it bugs me that he’s put it back in. Though, I do think that it is a brave and noble thing to put it back into his head, to deliberately give up the life that he won back. That’s who Chuck is.
The reason I’m concerned is that my initial worry is that this ending could be a bit of a deus ex machina, causing Chuck to go back to the Buy More, Sarah breaking off the relationship citing that she’s protecting him again and needs to remain professional, essentially doing a reset to season 1 with a new baddie; it would feel a bit of a cop-out. That being said, if they use this to take the show in an entirely new direction (ie Chuck, Sarah and John take off as real agents) this could get VERY interesting, and you’re right in that the new Intersect could result in some very humorous scenes.
Don’t get me wrong, assuming Chuck continues into season 3, I’ll definitely be watching! I guess the reason I’m passionate about this is because I like the series so much…
