I've watched every single episode and all the movies. Only thing I haven't seen was the cartoon series they tried to spin off, but it didn't do so well so looks like I didn't miss out on much.

Personally, once O'Neil was promoted and even when he was frozen it went kinda downhill since it started getting a bit mundane with the villains and save the world stuff. Still not a bad series, but it had its time and did well.
