I found Paul to be a bit flat. It did have some good bits but it wasn't funny enough to be a comedy and it wasn't interesting enough to be an alien movie.

maybe that's just me.

It's probably not just you, I'm sure there are others who would agree. But I can say my friends and I, and the audience we saw it with, were lolling on the reg. I think the sheer number of geek-cred nods alone earned it half a star (the Cantina Band song played by a country western bar band was particularly funny to me). In all, I'd give it a 7.5/10.

This morning I watched Billy Wilder's Witness for the Prosecution. Not my favorite Wilder flick, but great performances by Charles Laughton and Tyrone Power (I'm not a Marlene Dietrich fan, and she didn't do anything unique in this film to change that). Agatha Christie movies can be hard for me to enjoy, because I'm always expecting the unexpected and trying to figure out how she's going to trick us at the end. Sometimes her plots are too convoluted to be believed, but this one really worked for me.

EDIT: Damn, Ruta Lee was fiiine in 1957.
