Insurrection was what a TOS movie would have been if Friday's Child hadn't been an episode but instead a feature-length film.^Insurrection was the first Trek film that really felt like a direct to video B grader. It wasn't only just a two-part TNG ep, but it wouldn't have even been a very good two part TV episode.
The similarities are striking--heathen natives we care nothing about, Enterprise called away, rather uninspiring villains, stupid costumes. At least Friday's Child had those cool boomerangs. Then again, Insurrection had those badass Son'a battleships, which looked like boomerangs.
