I ran into an old movie I had on VHS as a kid titled "MegaForce" (1982) (RT link). I hadn't seen the movie in decades and was worried looking at a rotten tomato score of 6% that if I watched it, I would be completely disappointed in the movie as an adult. Surprisingly, I didn't realize as a kid that it was actually more of a spoof comedy action movie like a knock-off "Hot Shots" or "Naked Gun" and just completely enjoyed watching it again because it felt like a whole new experience (definitely better than the new G.I. Joe's lol).
So what's your movie from your past that you'll always enjoy no matter how cheesy or horrible it may seem?
Pretty much everything I liked as a kid I am lukewarm to now. However, there are a number of kid's books that I didn't "get" as a kid that I adore now
