John Tvs here with a quick review of "Cool World"! In my honest opinion, the film is pretty good, and has a pretty easy-to-follow story to go with it. Some of the characters (like Nails The Spider, Vincent Van Wrinkle, and Holli's Goons) are pretty creatively-designed and funny.
However, I feel as though the movie focuses too much on giving laughs through the various different random animations throughout the film and the dreaded sex-scene rather than actually providing constructive character development. You never see the Goons again after Holli becomes real, and most of the characters never change throughout the movie. Frank Harris is okay, but Jack Deebs is just some confused guy walking around in a cartoon world who has (*uh...*) with Holli for no good reason. Holli isn't even that well-written, as she's just a rip-off with Jessica Rabbit with MORE revealing clothes.
Should you watch this film? For the laughs, yes. But for everything else, I'd say a strong maybe, since this film is PG-13, despite being pretty vulgar for that rating. Also, Holli Would is just there as a selling point of the film, so if you're watching this film, and you're under 18, just skip through the cartoon sex scene. Your eyes will thank you!!
