This is a TV made film starring the tiny genius character that kids have grown to love on Cartoon Network. Basically Dexter is working peacefully in his lab, and being distracted by Dee Dee for a while. Meanwhile, his nemesis Mandark has created a small green power source or something. Dexter decides to see how he apparently saved the future. He is accompanied by mid future Dexter, far future Dexter and later warrior Dexter. They all fight against their own times Mandarks as well. In the end the four Dexters find out it wasn't them that saved the future, it was Dee Dee. Quite a good TV made film for a good cartoon show. Good!

The show is really good and this movie is great too! It has a more serious story line that's true, but the overall humor and great characters bring the whole thing together so that it fits like a glove! The whole style is awesome too, the coloring is real good, varying from the green colorful dexter scheme to the dark red Mandark scheme (which in one moment overrules the entire world). The robot in the fighting sequence is unbelievably good designed and the ending is as unexpected as it is hilarious! I can't believe some people rate this as a bad movie. The only thing that is negative is it's duration, I'd like to have seen a evening filling dexter presentation.

My young son is a big fan of the TV show and I usually get a chuckle out of the goofy family Dexter is forced to deal with, so we grabbed this from the rental shelf to check it out.The movie is all about Dexter (present and future) and his nemesis, Mandark. There is little of sister DeeDee, and no sign of glove-wearing mom or good old dad. Dexter travels forward in time, then forward still further, then back a little between the first two jumps (I think) in order to meet his future self who he believes "saved the future". He meets and joins up with future versions of himself who are all quite different from present Dexter.This normally brightly colored cartoon was fairly monochrome in this long feature, and the time jumping was hard to follow a viewer of any age. It lacked the usual characters and laughs of a short episode, but it wasn't meant to be Shrek or anything... (5/10)BTW - the only part to make me and my son laugh out loud was at the very end when all the Dexter's were saying their farewells... Goodbye Billy! Some more flat out humor and less misery would have been nice.

I love the show, it was great. The movie on the other hand, stunk. I'm glad they decided to make the movie, but not this one. The show is funny - filled with little tidbits that appeal to older as well as younger viewers. The movie was dark, unfunny, and very simple. It seems as if they just decided they needed to write a movie and made one before they got a good idea for it. (5/10)
