I consider this television special to be the real ending of the "Dexter's Laboratory" cartoon. It gave an appropriate closure to the Dexter/Mandark rivalry showing their respective futures in an almost "epic" scale. Is a completely satisfying resolution, so there is no need to watch any of the episodes that were produced after this (I'm talking about the episodes from the last two seasons that were made without Genndy Tartakovsky which were awful, had boring plots and a horrible animation style.)This movie was cool and well made, and it was very entertaining to watch, having all the good elements that made the series popular in first place. And the funny ending, after all the seriousness was a nice touch in my opinion.

Even if i am writing this review 13 years after the movies release, this is still my most favorite cartoon movie ever. The storyline was pure gold, its action scenes were amazing, the pure funniness in every scene, and the inappropriateness of it all was GENIUS! Old-Man Dexter just made me laugh to the verge of crying. Although there are a few frightening scenes throughout, the funniness overpowers the whole movie! The fight between dexter and the robots in the beginning were awesome! Dexter's use of the wrench made it seem like a killing machine. And the animation was very clean and smooth. too bad it was never longer than 1 hour, then the movie would've become a near classic.

Finally! Cartoon Network surprises us with a kick-butt movie! Genndy shows us an awesome finale to the series, filled with Action, Adventure, and a load of Dexter comedy that the new series lacks significantly (probibly cause he's not in it.) Anyways, the movie shows us the future in the dexter universe and reveals many new pieces in the show. I remember when I first saw it on a Sunday morning after taping it the night b4. It retains all the quality and Hana-Barbera goodness we don't see now, after it became Cartoon Network Studios. This should have been the last entry into the series, (as Genny wanted,) but was continued with not much of acception, (i didn't like it either,) My advise: If you liked "Last but not Beast" you'll love this one..... I hope.Simply funny. The Phantom

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.
