Ignore the people saying to start with SNW. Start with season 2 of TNG, then go to season 2 of DS9 after finishing TNG, then you’re good. From there you can pick whatever you want, but nothing will ever be as good again. TOS can be fun, but it’s very dated and campy. The TOS movies are lots of fun, especially the one with the whales. Double dumb ass on you!
Are the TNG movies worth watching in your opinion? If so, should i watch TOS and TOS movies before TNG ones?
They’re okay, not great, not bad, just okay. There are references to the original crew of the Enterprise in the TNG show a few times, but I don’t remember any references in the movies. I think they can all be watched as stand-alone movies except for the Star Trek: Nemesis movie because there’s a major plot development in it.
