DeeDeemensional (Dexter's Laboratory)

"DeeDeemensional" is the first part of the first episode in the first season of Dexter's Laboratory.

Plot
Dexter falls victim to one of his own inventions and sends Dee Dee back in time to warn his past self about the consequences, but the past Dexter proves hard to convince.

Why It Rocks

 * 1) It's the very first episode of Dexter's Laboratory, meaning that we get introduced to the things that made the show great - including Dexter, a person who is obsessed with science, Dee Dee, his older sister who messes them up, his laboratory, and so much more!
 * 2) The plot is very creative here, as it has Dexter getting eaten by a giant octopus monster and tells Dee Dee to go back to before it happened and must warn the past Dexter about the consequences.
 * 3) The dance the two Dee Dees do when on a stage with Dexter is pretty good to watch.
 * 4) The monster that eats Dexter at the start & later on has a pretty cool design.
 * 5) Funny Ending: Although Dexter still gets eaten by the octopus, Dee Dee gives him a message and then the two clones go back in time to warn the past Dexter once again.

Bad Qualities

 * 1) There's a few animation errors, where Dee Dee's voice goes out of sync when saying that Dexter is mean, and Dee Dee and her clone's tights disappear in one shot when she said "I remember this part!"
 * 2) We never get to see Dexter's problem be fixed and it ends up with Dexter sending the two Dee Dees back to the past, again.

Reception

 * It holds a rating of 7.6/10 on IMDB.
