I recall there was a Ben 10 thread somewhere in here, but seems that the thread died.
Omniverse.....it's an okay show, I guess. It has its flaws, though.
The fact that AF and UA are more serious is because Ben has grown up. Seriously, do you really expect him to stay like a 10 year old? This is what makes me dislike Omniverse Ben, his redesign makes him looks younger, and he acts more like his 10 year old self. It's not that I dislike the less serious approach, but I'm sure they could have given the series more humor without having to basically de-age Ben.....
Then there's the redesigns of the aliens and other characters.
Some are good (I like the new Jury Rigg much more now that he doesn't look that much like a devil - now if only they can remove that tail)
But some others are just horrible (Gwen in both timeline, especially the current timeline, they basically DESTROYED her. Not to mention her annoyingly bad new Anodite form. Alien X, Big Chill, and Echo Echo also have bad redesigns. And what's the point of Swampfire's redesign??? It's barely noticeable.....they might as well not redesign it at all)
Another thing I never understand : If I recall correctly, Azmuth thinks that the Ultimate addition will bring trouble. However, he fixed it anyway and Ben is even shown to be able to use them properly. So why did he not add the Ultimate feature into the new Omnitrix? It would have been interesting to see more Ultimate aliens.....but now that the feature basically doesn't exist, the chance for that to happen is zero -_-
Hopefully with the return of Ultimate aliens from Albedo, something happens that lets Ben use Ultimate aliens again, or Azmuth upgrades the Omnitrix with Ultimate feature.
And what's with the lack of female main character? I'll even accept that little Kineceleran girl in pink jacket as a new female main character, as long as there's one. It gets kinda boring sometimes if all we have are two boys.
