Zombies!
Wow, I'm completly blown away after watching this movie. This is really a flash master-piece. Like a lot people I did think that the Resident Evil Movie similarities was uncanny, but who the hell cares? Your movie still kicked ass.
Now the bad stuff! Voice acting got choppy at times, some scenes lagged on (especially the ship flying over the city), and the animation tended to get worse (like the two ship operators) But these few downsides don't really detract from the overall awesomeness of this movie.
Make parts 5&6 soon!
