The first time I watched it was in this (somewhat smelly) indie movie house. The sound was muffled and it was incredibly hard to make out what anyone said.
I was excited to go see it, but with the bad sound and just confusing elements, I left really unsure of it and what I just saw. I, and this is quite common with me, had the feeling that there could've been more to it that really would've escalated the experience, but there wasn't. The story (that everyone was dieing to figure out) was such a jagged step to conclusion, that I just still didn't figure out what the heck happened. It's such a wierd movie, and I'm entirely not sure of whether or not I liked it.
Interestingly, even you don't know with that "I think..." haha... it just does that!
