The last movie I went out of my way to watch was Paprika, an animated movie involving dreams that made me think "Hey, inception..." the whole time through.

I found the DVD of it with a $2 sticker in one of the game storage rooms at work and decided to grab it - yep, it was definitely worth the $2, I'd gladly sit down to watch it again.

Spoiler:

Paprika came first, although Inception is unique.
