Congo. I LOVED this movie as a kid. I watched it every day after school for close to two months. I just saw that it is getting a special edition physical release, and I will be buying it.
Batman & Robin. Again, I was a kid when this came out, so I didn't mind all the campy and weird things. I just loved it all. Plus, Chris O'Donnell as Robin was an early crush. I still love this movie.
Superman IV: The Quest for Peace. So corny and so bad yet I can see the, well, maybe not greatness but something close, that this movie could have been had it had a decent budget and competent people working on it.
EuroTrip: A very dated high school comedy from 2004 that still makes me laugh to this day. I watch it at least once a year.
