Dexter's Laboratory

Cartoon Network 1995

Dexter's Laboratory is the story of a young boy prodigy. Born with an extraordinary mind, Dexter has built his very own extremely high tech and expansive laboratory in his room that NASA could only dream of. But Dexter has to keep his lab a secret for fear others will exploit it. Through out the years, Dexter has had to hide his lab from his parents and others but it is no easy task. All Dexter wants is to spend all the time he can inventing new things in his lab, but between his stupid and annoying older sister Dee Dee constantly barging into his lab and tearing up the place and his arch enemy and rival genius Mandark constantly tiring to take over his lab, Dexter's life is anything but easy. Dexter's Laboratory was originally premiered on Cartoon Network as part of the inaugural, Space Ghost hosted, "World Premiere Toons" before becoming a feature with two full shorts on the regular series, a.k.a. the What a Cartoon Show, it eventually became a series itself.

It was funny when I was 8 years old and it is still funny even when I have 27. Great show. Cartoon Network classics forever.


This show still holds up 20 years later. The 1st 2 seasons will always be magnificent, they make me laugh just as much as they did back in my childhood. While the 3rd and 4th seasons weren't as good as the original, they were still decent enough in their own right. Re-watching this now I absolutely have no doubt that the 2 latter seasons get way too much hate but please just try to get used to the new art style and voice actors and I have no doubt that you'll come to enjoy them. My biggest issue is honestly that it does not have a proper series finale but hey I'm still grateful with what we got. Dexter and Dee Dee's antics will never get old to me and I especially like the episodes where they work together or look out for each other. Their Mom and Dad are just as crazy and funny as they are, with Dad being the funniest character of the series. I would try to name a favorite episode but I hold so many episodes in high regards that I'd probably write down more than 10 episodes as my favorites. The adult jokes are everywhere here so it is definitely worth re-watching in your adult years.

A little about me 👋 I am a marketing student in Paris. I love spending afternoons with friends in a cafe or a park.

But more than anything else, I love watching (.. binging…) series on my computer on rainy Sundays or any sunny day for that matter 🙈

I must have watched hundreds of shows by now, from romance to science-fiction series. Often I like to go back to a show I enjoyed. But I don’t feel like watching it all over again…

I created this website so myself and others could find the best episodes of our favourite shows. As of today, I have about 1,000 shows on the website with votes and rating coming from fans.

Hopefully, you can join me from your sofa and enjoy some nice TV!
