Pretty good
I can tell that a lot of hard work went into this movie, and it was a pretty good piece of work, but there are some things that need fixing that will improve your following movies a great deal.
1) sound.
a) the music for this vid was very similar, and all had very high tempos. music should accent the current event in the movie, not be like a fight scene throughout the entire movie.
b) the voices were very unclear, and the quality was very low. it would pay to practice with your mic to get better quality, and have the actors read their scripts a bit, the voice acting wasn't exactly top-notch.
2) many of the BGs and characters in your movies were very well drawn, such as samus and the police cars. however, your movies would be much better if the difference in art quality between characters wasn't so pronounced. it became distracting.
3) the biggest issue: animation. tweening is not everything, even though it makes animating much easier, it makes the movie look very unrealistic. tweens are great, but just like anything else, too much can spoil your work. (plus, the more advanced animation techniques look really cool ;)
sorry to be so critical, but being an artist myself, I know that the most helpful review is one that helps you to see flaws you didn't notice in your work.
overall, this was a good movie, and you should continue the series. keep up the good work.
