20. The Terminal (2004)
This film was unfairly maligned upon its release and has built up a reputation as one of Spielberg's worst films, but I actually find it to be surprisingly charming and quite underrated. It's not a great film by any means, and is definitely "lesser Spielberg", but it is certainly one of if not his funniest films, blessed by a truly brilliant central performance from Tom Hanks and a refreshing, interesting, and very successful premise. Sure, some of the sub-plots are a little saccharine, but every time Tom Hanks is on screen, the film is just irresistibly fun and entertaining.
