There's some 80s movies that are universally liked that I don't care for.
1. Raiders of the Lost Ark. I was born in 1979 so Temple of Doom was the first Indiana Jones movie I saw. I owned it and watched it dozens of times. I watched the Last Crusade in theaters and loved it, but I didn't get around to watching Raiders until right before Kingdom of the Crystal Skull came out. By then, I was 29 years old, Raiders was 27 years old, and it just felt dated. I'm sure I'd feel differently if I saw them in the correct order, but I'd still rank Raiders 3rd of the Indiana Jones movies.
2. The Goonies. Another classic kid 80s movie that for whatever reason, never saw as a kid. When I finally watched it as an adult, I thought it was meh.
3. Top Gun. The flying parts of the movie are great, but the other 75% of the movie absolutely sucks. Top Gun Maverick is awesome though.
4. ET: the movie never did anything for me. I think it's kind of boring.
Also, I think the overwhelming majority of James Bond movies are not very good, even the Sean Connery movies. I do like Goldfinger and Thunderball, but that's really it until Goldeneye. Daniel Craig is by far the best Bond.
Other than Spaceballs, which is a top 5 all time comedy, I don't find Mel Brooks movies to be that funny. (I haven't seen Young Frankenstein)
