I also saw it last weekend, without even knowing what it was or who made it. I liked it very much.
Half-way through I finally recognized Hugo Weaving's voice. Nathalie was fine, though 1 or 2 lines came out wrong ("I'm starving!").
Too much blood. I hated the blood. It wasn't even 'cool' violence...... just some slashing with liters of blood bursting out.
I LOVED the last scene with all the people coming up. ^-^
