Well, I finished the Star Wars trilogy tonight with episode VI, Return of the Jedi. I'd put it about on par with episode IV; pretty good. The Empire Strikes Back is definitely the best of the three, just like everyone seems to say. I had seen more of this one before today than I had episode V... probably about half of it or a little more.
In the end, I would probably say that The Empire Strikes Back could be "one of my favorite movies," though it certainly isn't in my top 10. I'm very glad that I forced myself to put aside my prejudice towards Star Wars and watch all three (five, actually... I got episodes I and II a couple months ago since they were becoming harder and harder to find) like this... were it not for Knights of the Old Republic (a recent Star Wars game for those of you living in caves), I never would have even considered picking them up. Overall a very worthwhile purchase, and probably something that no self-respecting nerd's movie collection should be without.
I'll just take this opportunity to tack on my opinion of Sky Captain and the World of Tomorrow, which I thought was well worth my $8.50 or whatever ridiculous amount movies cost here. It was a good movie, and its coolness factor was abnormally high. Unfortunately, its silliness was nearly off the charts at points, but it was done much better than movies I'd say were somewhat similar, like The League of Extraordinary Gentlemen. Sky Captain was inventive, interesting, and very well-filmed and produced. The story was interesting enough, and the characters were fun. As long as you can get past the fact that much of it is purposely stupid (like the Mystery Science Theatre-esque robots), I think that just about anyone could enjoy it.
