I'm probably going to catch some flack for this...
...but I actually really like the film and don't quite understand where all the hate is coming from.
Is it a perfect movie? Absolutely not. It is beautifully flawed. Maybe I see these things because I am also a filmmaker and not just a member of the general audience.
I thoroughly enjoyed the performances from the actors. I think they were all believable in their portrayals of their characters. Cameron Monaghan is very talented.
The writing... is probably the weakest link in the film. Some of the dialogue written could have been much better or more fleshed out. Obviously the plot holes could have been more thoroughly thought through as well.
In contrast to the writing, the style of the film is the strongest aspect to the piece. I loved the washed out colors and effects. Sure, most of it was nothing new. The distortion effects and morphing have been seen in previous LP music videos, chiefly New Divide and Burn It Down, but not everyone is familiar with those videos. These effects were tastefully incorporated into the world of cinema. It was an experimental approach and I feel it worked well.
Camera work was good. Though not great. It did its job. About half the time I felt like I was watching a music video. Other times the cinematic feel was perfectly achieved. I wonder how many camera ops or DP's were actually attached during production.
Music totally worked. I'd love to get my hands on the soundtrack. Another user pointed out in another thread that the music sounds like what was heard in the Resident Evil movies and I tend to agree. But that doesn't mean it's a bad thing necessarily.
Joe Hahn did a superb job for his directorial debut (whatever happened to King Rat? Was that ever made?). I look forward to his next films. Yes, that's plural :)
