Sequels that are better than the first ones.

I've never seen any of the Problem Child films (and probably never will), but the episode of Gilbert Gottfried's podcast with the writers of those films (Scott Alexander and
Larry Karaszewski--who would go on to write Ed Wood and The People vs. Larry Flynt) has some great behinds-the-scenes stuff on how the second film in that series, in particular, came to be.

gremlins 2
