One “bad” movie that isn’t actually bad (I will fight anyone who says otherwise) that I always cite in this regard of award noms is Armageddon. Not only are there at least 5 Oscar nominations in the cast, but three of those nominations are for WRITING (Affleck, Owen Wilson, Billy Bob Thornton). Then you’ve got a secondary cast that includes Steve Buscemi, Jason Isaacs, Will Patton, Keith David, and the awesome William Fichtner and Peter Stormare. Plus a script co-written by J.J. Abrams.
On top of all that, a pantheon-level quote: “What’re you doing with a gun in space?!”
