Some decent sound could have gone a long way...
Sound makes or breaks a movie, especially in this case. The graphics were static, so that means that you had to carry the movie on your voicing. Unfortunately, you didn't do enough with that. The voices were all whispery and samey. I would have loved to hear some bad Morpheus or Smith impressions, but you didn't seem to try very hard, and ended up with boring dialogue. The trinity-vampire thing was kinda funny, but one funny joke doesn't carry a movie. If the voicing were a little more spirited, then this would have been a much more interesting flash, but as it is, it just isn't anything special. Just be a little more spirited next time, that's all.
