Oh god.
The idea to start was really cliche, you need to be a lot more creative when writing a movie. I've seen just about everything in this movie already in some other feature, and I'm disappointing how oddly uneducated you seem to be in that field.
The voice actor sounds like bat man. He went way overboard trying to play that role as a cop who's had too much to take. Every time he talked it was just a reminder of how bad the movie as a whole is, because attempting at that voice for a serious plot is just sad. The voice didn't even match the character's looks.
The graphics were mediocre at best. You made larry taller than the computer as you zoomed in in his office, the blood particles were not even decent, the cloudy effects on the sun and clouds and stuff looked really filtery, which is bad in any movie because you never want to look like you spent 4 minutes making an effect in flash. The people weren't well drawn and it overall just doesn't look like you spent much time on what's important.
Now this review may look mean to you but really this is me trying to be helpful. If no one else is going to tell you that this is bad then maybe I should. It's healthy to be told that you're not good sometimes, especially when the foundation and execution of your projects are so low-key-looking.
I don't honestly see how the newgrounds staff could have possibly found this appealing enough to be on frontpage though. At least you're not as overblown as TETRIS'D otherwise it would take you a much longer time to read an authentically mean review. But good luck with your future stuff.
