I loved it but I don't think it would hold up a second time. I was eating dinner and drinking a margarita during it and I didn't finish the food or drink by the end of the film. It seemed like it just hypnotized me. It was just a good experience that I woudn't want to sully by watching it again and finding out it's just OK.
I do love a good concept album whether or not I can discern the concept myself or not.Take The Mars Volta's concept album "Frances the Mute". That album is fantastic (if not a little laborious at times listening to frogs for 4 minutes) but the concept can not be figured out just by reading the lyrics or listening to it imo. Now Mastodon's album "Crack the Skye" is a fairly easy story to follow and the music is great. I'm a fan of both. If I can't figure out the story myself that doesn't discredit the concept because the artist(s) who wrote it had the concept in their head the whole time.
