Alien Swarm is not as good as the cartoons series Ben 10, Alien Force and Ultimate Alien, but in every way it outdoes the disappointing-but-better-than-its-reputation Race Against Time. While the pace could have steadied a bit and it is lacking a bit in emotional depth particularly in the first half(though Ben does develop very well),the direction is far more assured and the actors fit the parts much better and feel more comfortable.

The production values are also an improvement, the photography, lighting and locations are very reasonable for a TV movie, and the effects are pretty great, especially with Big Chill and in the finale. The soundtrack is rousing, the script has its humorous and thought-provoking moments, the story unfolds very nicely with a strong underlying mystery and the action is well-choreographed particularly in the chase sequences.

Overall, a surprisingly good film and outdoes Race Against Time in every way. 8/10 Bethany Cox

This movie is just awesome I can't believe it has nearly been about 9 years ever since it had first realised. I really wished this movie was in theatres instead of crap like Dragon Ball Evolution and likely hood the Teen Titans Go! movie.

The acting was brilliant, the effects and CGI was perfect. However I wish Ben turned into more aliens because he only used Big Chill in the first battle with the Nanochips, Humangosaur to fight a giant ball of spikes the worst part was they only made him roar in the movie like they did to Hulk in the MCU and finally Nanomach for the final battle (Props go to Alex Winter for his voice). Kevin and Gwen used less of their powers as well. To be honest the actress who they chose for Gwen seemed pretty weak for the part because in one scene when she punched a mind controlled host she hurt her hand. However the actor for Ben who appear on Smallville for 2 episodes and the actor for kevin were good.

They are also gross moments involved like when Nanomech goes up Victors nose.

But other then it's few flaws it was actually a very awesome movie and it's definitely better the Race against time. If you are a fan of Ben 10 you might enjoy this.

Well not that great but not the worst either but you can watch it if you bored
