Get Smart starts out great with lots of laughs, but the humor fades away somewhat toward the middle and end. The big fight scene at the end is a bit boring on repeat watches. I still like watching the movie, though, and I recommend it.
The screenplay never takes any particularly sharp, or even interesting turns. Needless to say, North By Northwest is not in risk of losing its crown as the funniest and most-action packed mistaken-identity caper.
This was nothing like what I expected. The only reason the end of the movie was seen, was because my wife was watching it, also. She liked it, I didn't care for it. It's not his typical comedy you would expect.
