Hmm....
This was kinda bland, what with the lack of much definitive action and very little sound.
The graphics however, were patchy at times, while simply beautiful at others.
For example, I could see through the cars, and the headlong shot wasn't terribly impressive, and was kinda out of proportion.
HOWEVER, that part where the shadowy figure jumps from the window of the skyscraper, was impressive, and looked great. Just like the back-angle shot of his bloody hand...
The style was, like I said, bland. The action needs to be picked up, especially in such a short animation. The dialogue, needing to be read, is NOT good for an action-ey Flash. I don't want to be torn from a fight scene to read what they have to say.
Also, the grammar was kinda goofy. "I" should ALWAYS be capitolized (sorry, I'm just a bit picky about grammar).
The violence...was kinda absent. But that's alright in an introduction, just clears the way for more fighting nd blood and explosions, and death.
I liked the preloader, too.
Overall, this wasn't bad. Not the greatest thing I've ever seen, and has room for improvement, but definitely has a lot of potential.
I'd like to see that unlocked, and the cliche names avoided in the future.
HOWEVER, in short, I liked this. And I hope that the next in the series is just as good, and better, and that the pace is picked up, music is added, and there is more action.
Good luck!
