I saw this last Tuesday, a buddy of mine is a huge movie dork and gets advanced passes and he knows that the original is a movie I probably have seen 50 times.
I didn't want to give my 2 cents right away, I was worried anything I said would be spoilerish.
But... seeing what others have said I will give my "non-spoiler" review. It was even more over the top than the first film, Maverick probably could have been court-martialed 5 times. But it is wildly entertaining, very nostalgic. It's just a fun movie.
Literally my only complaint is that the sound track is not as good as the first film... but that is a hard hill to climb, because it's one of the greatest sound tracks of all time.
Side note: My dad served in the Air Force and flew F-5s, the "Mig 28" of the original flim. They're still around, mostly as T-38s, the super sonic trainer for the Air Force. But, mostly because of the original film, nothing is as cool as the F-14. In terms of fighter planes it is a massive aircraft, yet it had incredible maneuverability in low speed dog fights and virtually nothing could beat it at supersonic speed, both factors due to it's variable wing. A gorgeous aircraft. Too bad we sold a bunch to Iran and got paranoid about extending it's life span or it would likely still in service and upgraded today.
