No, not the f' bomb, though I was surprised when it happened. There's one scene with the High Evolutionary which fits more into a horror movie.
But my main thing, is it shows the brutality used in animal testing and science experiments, in gruesome detail. I personally found Rocket's fellow altered animal friends kind of scary / creepy to look at, which, of course was intended. Anyway, it's pretty intense stuff, and really isn't meant for young kids. Not sure about the Disney cartoons, but yes, kind of like when Bambi's mom's died ... but multiplied by 1000.
