Sonic 2: Return of the Jedi(?)
Ok, it was a bit better than your average sprite animation except for one small thing:
FPS
Make your FPS higher, because nobody wants to watch teleporting sprites. We all know it's the easiest form of animation in the world (except if you made sprites from stick figures... but then i guess at least they'd be your own creations) So we expect more out of a sprite based movie.
The text in the jungle part goes a little too fast in the middle. Slow it down a bit. Speed up the rest though, and try doing a couple of zooms and different camera shots - more effects! Otherwise those first two sequences get a bit tedious (especially the send one)
Overall i think it's obvious that you've got some potential with this, so keep at it!

PS - i like what you did with the lightsabers - looked like it actually belonged there! Congrats!
