Dexter's Laboratory was a Cartoon Network cornerstone in the late '90s, and for millennials, it's pure nostalgia. The premise is solid: a boy genius with a secret lab constantly thwarted by his chaotic sister. It celebrates science and creativity, which is great.

But here's the thing: it's really showing its age. The animation style, pacing, and humor feel distinctly 1996. Modern kids raised on shows like Bluey, The Owl House, or even newer Cartoon Network fare may find it visually unappealing and slow. The constant sibling antagonism—while relatable—can feel one-note and grating over multiple episodes.

It's not bad, but it's also not must-watch unless your kid is specifically into retro cartoons or you're looking for something science-themed. The WISE score reflects that it's wholesome enough and imaginative, but the watchability penalty is real. If your kid bounces off it after one episode, don't force it—there are better options that scratch the same itch.
