I've seen all the Star Wars original trilogy films probably a couple dozen times in the last 22 years. "Jedi" has kind of worn on me over the years; I can only really manage it in movie marathons, and even then I usually get distracted about half way through. The original is great, but once you've seen it...you've seen it. The plot is good - a great adventure with a iconic bad guy and pure-of-heart hero - but after once or twice I can probably quote it seen by seen.
Empire Strikes Back doesn't ever get old. It doesn't get worse, and after all these years I'm still finding new things about it that interest me all the more. Unfortunately for this discussion, that's the same way I feel about Inception. Two phenomenally casted movies, with brilliant plots that don't get old and keep revealing themselves the more you watch them.
Inception gets a lot of crap by more elitist fans because of Christopher Nolan, its monstrous budget, probably some for DiCaprio, and being overly (and intentionally) complicated. But um...in response, I'm going to go with...George Lucas, Harrison Ford, $11,000,000...in 1977, and *spoiler alert* Darth Vader being Luke's father.
No, I'm not saying Inception = Empire Strikes Back. I'm not even saying Inception > Empire Strikes Back. That would be silly. But they are both great films, and these days if I had to pop one in to enjoy an afternoon with a pizza and some friends, I'd go Inception. There may be such a thing as over-exposure; granted that goes both ways, I suppose.
