Saw it earlier. It was pretty entertaining. Not sure about "amazing" though, I think it took itself a bit too seriously considering its a guy in a big helmet who always (ALWAYS!) looks like he's shitting his pants.
But the slow-mo drug sequences were extremely well-done. I didn't plan on seeing this in 3D but the 3D was pretty good in those parts. I also liked his sidekick, she was very interesting and well-written. A few good laughs in there too as well as decent one-liners. It felt like it had the spirit of an old school Action film retooled for the modern age. Hope it does well and gets a sequel, i'm interested in what they plan to do with this franchise.
