I fell in love with the original one for it's sheer inventiveness and goofy characters. But Alien Force switches that up with even more inventiveness, but with mature characters now. It was a welcome change and did the series much good; it made room for new, somewhat darker ideas. Some episodes were, I felt, particularly ground breaking, such as Professor Paradox and The Vengeance of Vilgax, Part 2. Also, how could I not mention this, Alien X was amazing.

15-year-old Ben Tennyson must utilize the Omnitrix yet again in order to locate his missing Grandpa Max, accompanied by his cousin Gwen and former enemy Kevin 11. Ben 10 Alien Force is a sequel to the Ben 10 Original Series and this time the original characters (Ben, Gwen and Kevin) are all grown up and this time around? Their working together to save the Planet from Enemies beyond their imagination. The animation is great and the New Characters that Ben can transform are terrific especially the Humungousaur also some of the videogames that it got were good too and fans of the original series will definitely appreciate what Ben 10: Alien Force brings to the Table and it's sad that this show doesn't play on TV anymore and instead we got the New One which looks Awful and it is to be honest.

Like I said about the original, it wasn't a masterpiece, but at least it was a very amusing show to watch, but I agree that Ben 10: Alien Force is more mature and clever. Ben and Gwen in the original series were developed seeing how they've treated each other despite them having annoying moments in the episodes. In this series, Ben has now matured dramatically and is now close with Gwen. In the original, Kevin 11 wants revenge on Ben for turning him into a deformed combination of his aliens from the Omnitrix. In this series, he has changed from bad to good and is now helping Ben fight off new evil doers along with old ones. And the part where Ben finally has a girlfriend named Julie was amazing and their romance was developed enough. That's it for the contrast of this show and the previous. The animation is pretty detailed and the character designs were unique with some new talented voice actors to make them likable. The new aliens from the now altered omnitrix (now a watch, which was totally cool) were amazing with their new super powers. The sci-fi action is amazingly intense and the stories for the show are much darker than the original thanks to its clever writing. Ben 10: Alien Force would always be recommended to fans as one of the greatest TV shows ever made.

Ben 10: Alien Force, in my humble opinion, is entirely superior to the original. As the characters have matured, the story has followed. The series has grown much darker, and it fits in surprisingly well, considering the general lightheartedness of the original series.The characters have not only aged, but they've developed quite well with their surroundings. The formerly goofy and energetic Ben is much more collected (aside from the many situations where his powers take over). The villains are much more sinister, but balanced, showing signs of weakness in many situations while remaining incredibly intimidating.While the name puns are still rather weak, it's a staple in the series, and just feel in place.Ben 10: Alien Force is one of those rare gems that shows that great effort is put into making every episode. A must watch if you liked the original, worth looking into even if you didn't.
