It's got a very TOS-style of writing and story to it.

I remember seeing a fair few people pitch a fit about the Burn, for example, even though "angry man has a tantrum and nearly blows up the universe", and "child with godlike powers" are common TOS plots.

They tried something new, which I don't mind them for, but I don't think it mixed well with people being used to more TNG-styles plots, and the writing not being that great. Still, it managed to help kickstart the modern revival of Trek, and gave us (non-wheelchair) Captain Pike, so it wasn't all bad.
