A turd in a stocking.
Yet another awful Flash made by you. It suffers from the exact same problems as all your other Flashes. Problems which I have pointed out to you on numerous occasions, yet you seem to do nothing about it.
The graphics were rushed and didn't look good at all. It would have been nice if you'd put a little time in to getting them to at least look alright. As always the animation was absolutely hideous, since apart from one character for 3 seconds, nothing whatsoever was redrawn, which made the movement look completely wrong. If you weren't going to bother to redraw various things, you should have motion tweened rather than moving all the bits a little bit in each seperate frame. That way the movement would have flowed smoothly rather than being choppy, which made this animation even worse than it already was. The backgrounds were even worse than the characters themselves. Modify>Bitmap>Trace Bitmap seldom looks good. Using these awful backgrounds throughout the entire Flash was far from a good idea. The worst part of this Flash graphics-wise were the white things at the start with text on, since I have no idea what they supposed to be, since again they were rushed drawings.
Again the choices of sound was awful. The footsteps sounded wrong and were also too loud and irritating. The voice acting was horrendous and at times it wasn't too easy to understand due to the sound quality being so bad. Subtitles would have been a welcome addition.
The story was extremely dull and completley lacked any originality, making this a chore to sit through. Try putting a little more thought into what exactly you're going to make. A good storyline is the most important thing when it comes to a movie. If there isn't one, the audience will find themselves extremely bored. The Flash was made even worse by the awful attempts at humour; an exploding present, aliens being sent flying through the air, aliens falling over and some other completely unoriginal, unfunny jokes thrown in.
When you make your next Flash bear these things in mind, otherwise you're going to end up with yet another hideous Flash to your name.
