What are the most underrated films of all time?

Red Tails

[Mr. Smith]

Other underrated ones:

The first two Harry Potter films: Mr. Dule was just wrong. The direction had a certain whimsy and fun that the other movies lacked, ironic considering the upped budget. Richard Harris was iconic as Dumbledore. Maggie Smith, Alan Rickman were top notch... but so was Jason Isaacs [aka Zhukov], oh and Brannagh as Lockhart. But yes, the kids were actually quite well cast. It's lamentable that so much got lost after Columbus left.

Star Wars Episodes 1 and 3: The Phantom Menace is not the worst film of all time. It was deeply flawed, but really it was more like there were too many subplots as opposed to necessarily any one wrong thing. Finally, Revenge of the Sith was very well written, but very questionably directed.

Steven Spielberg's Hook: Often considered one of his lesser films, but sans two weird scenes, I found it to be one of the better interpretations of Peter Pan. Robin Williams was amazing, Dante Basco was an excellent character

Wide Awake: An early M. Night Shyamalan film about the exploration of an afterlife and death, the actin was actually quite amazing since it was back in the days when Shyamalan simply avoided overacting rather than simply no emotion.

Milk: Biopics tend to be looked at quite cynically, often treated as Oscar Bait...but this is one of the better ones. It's one of Sean Penn's far more sincere performances [he's simply too pretentious most of the time]

Ed Wood: Arguably one of Tim Burton's best, but also seriously not talked about. It's sad.

Charlie and the Chocolate Factory: Even if Johnny Depp didn't give one of his better performances and Tim Burton was definitely less up to snuff than usual, it still had amazin' child performances and tried to give more depth to the story...as opposed to the 70's version, which has nothin' going for it except Gene Wilder.

The Godfather Part III: It was meant to be a coda, not a similar epic like the first two parts. With that, I'd say it mostly does the job well. Al Pacino did the Al Pacino-y thing, and the subplots with The Vatican were pretty good. Really, the only real hurdle to this film is the casting of Andy Garcia...and how badly written Mary Corleone was...that's right, I don't think anyone could have saved that role...so Sofia Coppola did no harm.
