I actually quite enjoyed this. Though overlong it absolutely is. Reading a few reviews after watching it I think too many people took it far too seriously rather than being nothing more than a pastiche of pulpy B movie fiction that focuses entirely on the oddities in the LA movie that wears its influences on its sleeve.
And I really dislike how every discussion on some sites such as Facebook turn into "it's too complex for you, you just weren't smart enough to get it!"
I understood the movie just fine. Still thought the movie was just fine.
