I haven't really paid attention to this series, but as an individual movie; it's good.
Graphics: Great job on importing the sprites and cautious use of blur effects. I don't have a problem with flash made out of sprites as long as the movie is good. Plus, it was also a smart move to do many of the blur effects with Photoshop rather than do it directly in flash. However, aside from the custom palettes and aforementioned blur; there wasn't much in terms of customization.
Sound: Great job on the sound effects, and I liked the non-use of voice acting. It's a breath of fresh air after hearing the same damned voice actors over and over again. On the other hand, the music while good, isn't really fitting for a series finale. I think that you should have gotten some music from the Audio Portal. (Examples: Bosa, Waterflame, Xarnor, Box-Killa, and Nemesis Theory come to mind.)
Content: Goddamn, your fight choreography was fucking amazing! It may not have the wow factor that Alvin Earthworm has, but it was solid none-the-less. While a lot of people may bitch at the lack of cinematography; the fact that it was easy to follow made up for that. Of course, the story may not be up to par with Dual Arms or Cooljaw, it was solid. On the other hand, this isn't that much different from similar flash aside from the SNK and Melty Blood characters.
The Good:
-Great spritework
-Excellent direction and choreography
-Fitting sound effects and non-use of voices
-Top-notch pace
-Decent plot
The Bad:
-Not that much different from similar flash.
-Could have used better music
Overall: Here's a nine out of ten from me. (4.5/5)
