Metropolis is on Netflix right now if you feel like giving it a second go. It's totally understandable if you don't want to though. Sometimes it seems that despite their charms, silent films take a bit of extra effort to watch.
The Day the Earth Stood Still was pretty good. It didn't feel cheap at all and it was kind of refreshing that the movie gets straight to the point without a lot of buildup, though on the flip side, that ending was abrupt as hell. It's kind of interesting as well that it's a very plot driven movie, and while a lot happens, and what happens is significant, it didn't really feel all that profound. It seems like there were quite a few times where they seemed more than ready to jump into some philosophical aspects, only to just scratch the surface and leave the viewer hanging a bit.
All in all though, it was pretty good. I might see if some of my friends would want to watch it with me.
