I never had that lovin' feeling. :(
Also, if you listen to the audio commentary on the Blu-ray/DVD, a number of NAs and NFOs chime in on the matter. Top Gun was a more realistic film than it was given credit for. It's still no documentary, but it's not like there was no attempt made to make it true-to-life.
The sequel can be great as long it doesn't try to be like the first one. Look at this remark from director Joe Kosinski:
So I think the director is keenly aware Top Gun 2 has to be a different film from what the original was in order to be successful. I also get a sense that it may take a more serious tone, given the fact our NAs and NFOs have been fighting wars for almost 20 years now. In other words, play time is over.
