I know those two are, but I love them. Unironically. I've read the Waterworld comics, I bought the Arrow bluray release with the Ulysses cut the day it came out. I'm tempted to get a copy of Waterworld for my Virtual Boy to round out the collection.
Battlefield Earth isn't on the same level as Waterworld, but I still read the book after watching it and love the movie even more, having the whole story filled in.
