Again, thanks for all the input !
Time Force and Dino Charge for me. I never got into RPM, it landed in the space between "I guess I'm too old for this" and "nostalgic rediscovery".
How did you like the first few series? I rewatched some episodes recently and it was a lot more overtly cheesy than I remember. Still great nostalgia though.
As a kid I watched up to the middle of Turbo every saturday morning, Power Rangers was my religion back then, so it was really fun to dive back in.
The acting definitely needed to get used to, some episodes where REALLY bad, mostly when they were voice acting over Sentai scenes. I guess it helps a lot if you actually play your character instead of just saying his lines. Overall it's a really fun thing to do, a huge nostalgia trip and there really are some great and memorable episodes. The only thing that I really dislike is the insane amount of Deux Ex Machina they pull out of their asses. As a kid you'd think "oh wow they are so lucky to find the keys to new zords right after getting the current zords destroyed!", but now after binge watching it and realizing this happens about every 20 episodes, it's really annoying.
Also they resolve some issues way too quickly, like this morning I was watching the episode of PR in Space where TJ loses his memory. It took him like 2 minutes to get it back, there's absolutely no real impact from something that could have been an interesting minor story arc. And it's always like this, a cool premise that gets resolved in a matter of minutes, if not even seconds.
Zeo was way worse than I remembered, but Turbo is definitely the low point on the early PR series imo. I just hated Justin back then, now I understand that it must have really been difficult for the kid to play on such a show. Poor lad. Also the fact that suddenly you don't have anyone from the OG cast remaining and the fact that the characters are way less interesting (even though they are less stereotypical than before) is hurting the show a lot.
PR in Space so far is actually really good and the first series that I didn't watch at all as a kid. It's hilarious how many Star Wars references they are making as well (the dagoba system, Alpha 6 saying "I sense a disturbance in the force", and so on).
Overall I'd rate the Zordon era, as of now, like this:
Mighty Morphin S1 > MM S3 > in Space > MM S2 > Zeo > Turbo
