Fridge Horror: During the scene after Android 17 blows up the refugees Trunks had been trying to save, the camera seems to be avoiding showing the ground at certain angles around Trunks. It's slightly disturbing, seemingly for no reason, until you realize there are probably more corpses and/or corpse pieces scattered around in the places the audience can't see.
Narm: Some of the dialogue may come across this way. Android 17 calling humans "vermin" seems to be the one that stands out.
Some viewers found the series more frightening than the already dark original special because Trunks is played by an actual child- it's scarier to see a kid being beaten up by a pair of cyborgs in live action than in anime.
The crew manages to capture the raw speed/strength of the franchise's fights very well, and the special effects for energy (ki or the Androids' variant) aren't too shabby either.
The fight scene in the pilot gets much more exciting once Gohan transforms.
