Hmmm....what I can come up with that I think no one else likes is bound to get disproven on this thread. For the most part the theme seems to be films that involve Stallone that I loved as a kid but wasn't sophisticated enough at the time to realize they are garbage - and choose to say I still like them because I don't want to turn my back on my youth.
Rambo, First Blood Part 2
Rocky III (Mr. T and Hulk Hogan!)
Rocky IV (James Brown cameo...and training montage in Russia, are you kidding me??? AND, he practically ends the cold war with his moving post victory speech
Also, I have always been a huge fan of the movie "Real Genius" with Val Kilmer. I'd venture to say lots of people like this movie, but I honestly don't know anyone who's familiar with it. I'm not sure where I heard this (it may have likely been on TDPF) but the character Laslo supposedly is loosely based on local legend Tunnel Bob.
