Fanciful, disturbing, and wildly original, it announces the arrival of a fresh, bold voice in American cinema.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

"Spoiler free review"I think all the fans and I should know that this was intended to be the very last of the series as of what Genndy Tartakovsky wanted. I loved Dexter's Laboratory when I was young even though I always got mad at DeeDee whenever she destroyed something for Dexter, but luckily we don't get to see her much in the whole movie. But the first time I saw this movie when I was 7 I think, I thought the movie was too awesome and wanted to see it again and again. Watching it again I could still feel the awesomeness but at the same time I could see clearly how the movie got some flaws. The flaws isn't exactly annoying or horrible to watch, but because of it's time limit it will likely not explain everything.The animation itself is as the series very good and concentrated. Genndy and the crew did a very good job to make sure the movie still had the same feeling as the series. The story itself is quite different but a good story boarding to tell how the young Dexter decides to see the one who saved the future which of course he believe he did it. But suddenly comes across with the other Dexter's of himself in the future. The adult or wimpy Dexter, the old Dexter and of course the Action Dexter (Suddenly Dexter became rugged as his favorite TV-hero Action Hank). They were all different except still having their genius intelligence. The music is more epic and loyal to Dexter on his personal mission.As what I said about the flaws, the problem of the story might be of it's time limit. If only the movie were longer I think it would make the movie more interesting and deeper to the time traveling and the older Dexter's life. It also lacked some characters but I guess that Genndy were mostly concentrating on the Dexter and Mandark rivalry. Concentrating on the older Dexter's they might give you a different feeling to them like they are the supporting characters instead of they are the original Dexter. Some people were criticizing about the lack of humor, in my opinion I found the humor to be enough to entertain myself with the way Dexter's Lab is. The old Dexter was the funniest character in the whole movie.So all in all this less than 50 minutes movie was still entertaining and is definitely a more loyal and good ending to one of Cartoon Network's masterpieces. Despite it's flaws I still think the movie is worth watching how many times you want, but you definitely need to be a Dexter's Lab fan and you must have some philosophical interests especially when it comes to time traveling. Not perfect but a perfect ending and premise to the series."A little comment to CommonSenseMedia"(The movie itself is not sexist at all and just because of it's beginning it doesn't make the whole movie sexist and inappropriate to children. It's not trippy either. I think that you should not worry so much about what the movie gives. This movie is at least not to bad to show the children. And maybe the movie indeed is aimed for young boys but there are girls that can as well enjoy it too.)

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.

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!

I personally enjoy Dexter's Lab, and watch it whenever I can. When "Ego Trip" was first put on TV in 1999, my brother and I made sure we had a blank tape to record it on. It goes along with the typical "Dexter" style, including animation, which naturally isn't entirely the best. Even so, I found the movie very funny and enjoyable, with a good ending - following the typical style of Dexter's Lab where it kind of leaves you a bit hanging at the end. I recommend this to all people who enjoy the show "Dexter's Lab."
