I thought it was great fun. Couldn't believe how violent it was - this was no Rob Schneider co-starrer, that's for sure. I thought Urban totally nailed the character and I loved the grimy lived-in look of MC1 and the uniforms and hardware. I didn't miss the flying bikes at all.
I'll probably go again, as I'd arranged to go with one mate, who couldn't make it last night and then I went spur-of-the-moment with another friend. I saw a 2D showing today, so I'll try to get to a 3D next time.
