Satyricon is so great. I really, REALLY need to own that.
Ehh.... I'm so torn on this.
On the one hand, the script completely blows. The dialog is, at best, kind of clunky (at worst, completely facepalm-worthy), there's very little in the way of character development in places it's sort of required--like when your primary villain has no real motivation, you have a problem--and it feels like a huge part of the early part of the plot is just kind of ignored/brushed aside (WTF is "Unobtanium"--why are they even on the damn planet, really).
On the other hand, it's SO GODDAMN PRETTY. The production design just makes it so engaging to watch, it pretty successfully takes you out of how dumb the script is for a pretty large chunk of the running time. And given how dumb the script is (and the drawn out running time), that's saying a lot.
So I kind of hate that I enjoyed it, but I would totally watch it again. It's frustrating though--if Cameron had given his script to a better (more subtle) writer, it could've been SO good. The story arc is a little cliche, but there's potential there--the mythological framework is great, and again, SO GODDAMN PRETTY.
