Surprisingly better than the first Ben 10
12 June 2009 | by (New Zealand) – See all my reviews

My little brother watches Ben 10 and Ben 10 Alien Force. I took a look at them myself and both are really good, but Alien Force has made a lot of improvement, I have to admit. Almost everything about Alien Force is better than Ben 10. Let me talk about it.

The characters have matured and that is actually a good thing. I often felt that the character relationship between Ben and Gwen in the original series was pretty over-done seeing how they treat each other. In this Ben 10 series, they are quite close and it actually works well. Kevin Levin was an evil brute who used his powers only for his satisfaction in the old Ben 10. Now, he is encouraged to work with them as they learn that Max Tennyson went missing on a plumber's case and they try to find him. The characters are a lot better than in the first and have far better design. The voices in this series is better than the previous as it makes the characters more unique and likable.

The stories in the episodes are much better as well. The episode's stories themselves prove that Alien Force is for older kids. The reason is that the plots may be a lot more difficult to understand and are a bit more complex. Nevertheless, just as the series and Ben himself have grown up, the targeting audience from Ben 10 has grown up as well. It is a bit less violent, but has a much darker feel due to the improvement in animation and tension and is more confusing for little kids.

This series also has better music than the original Ben 10 and more detailed fight scenes and even more unique and detailed alien designs. In Alien Force, Ben changes into totally different E.T.s when he is about to fight. Ones like Swampfire, Humoungosaur and Brainstorm all feel very original and more interesting types of aliens.

Though I was originally a fan of the first Ben 10, I have changed my mind for Ben 10 Alien Force. Ben 10 is good for kids to start off with then, and Alien Force is good for them to view when they have grown out of the original Ben 10. I will definitely say that Ben 10 Alien Force is better than the first due to its improvements.
