[TokuChris]

I've seen almost every episode with the exception of some "Wild Force", "Operation Overdrive", and "Jungle Fury" episodes. Here's a brief rating from me:

MMPR S1 - Really campy. Improved towards the end.
MMPR S2 - Took everything from S1 and improved it ten fold.
MMPR S3 - Took giant steps backwards.
Zeo - Great story-telling and characterization for all characters. Great cast.
Turbo - Behind the scenes drama made first half boring, second half uninteresting.
In Space - Once out of the light of "replacing old Rangers", cast really came in to their own. Great original story, great cast, great everything.
Lost Galaxy - Great premise, poor execution, especially towards the end with cast members walking off set.
Lightspeed Rescue - Underrated. Music was bland, made scenes uninteresting, otherwise could be a top season.
Time Force - Best cast since Zeo/In Space. Great storyline. You cared about the characters and their stories. Wes/Eric/Jen will always be fan favorites.
Wild Force - Great potential but influx situation from Saban to Disney hurt the show. Princess Sheila ruined a good portion of the scenes.
Ninja Storm - Great throw-back to the days of MMPR. Was fun and light-hearted, but serious when needed.
Dino Thunder - Great homage to past fans. Best episode ever in "Fighting Spirit".
SPD - Great set-up, great cast, budget shortfall and random ending hurt it
Mystic Force - Underrated, good cast, Sentai footage really limited potential
Operation Overdrive - Executive Producer didn't care anymore and it shows, show suffered until the team-up and Mack's revelation. Sentinel Knight was the worst voice-over ever.
Jungle Fury - RJ and the Spirit Rangers are the only saving graces about this season.
RPM - Best season of the entire franchise, only because the Executive Producer wanted the show to go out with a bang and make it all his own. Summer was annoying. Could have used a protagnoist (ie: Bulk and Skull, Dillon and Cassidy, etc.)
Samurai - Weak start, better in the middle, we'll see how the last half does.
