I can't speak for Mystery Men, but I thought Galaxy Quest gets talked about in a positive light every time it's brought up. Outside of critics, I don't think I've seen people talk shit about Galaxy Quest.
People hated Hook? I never knew. I watched that movie a ton as a kid.
Fievel Goes West was as respected as the 90s Disney movies at home.
Absolutely loved this growing up. Was surprised when I found it out reception wasn't very good lol
