The original has the nostalgia of being the first I ever saw when I was so young but i'd definitely say Space was the best. I stopped watching after that so I don't know about lost galaxy or anything after that.

The original. When I was a kid I never missed an episode.

I grew up with the original. But the one where the asian guy over emotes everything to the 10th degree is just too funny to not love.

The Original Heroes 

After In Space, the series sucked. The originals were always the best despite being absolutely cheesy and stupid.

I forgot about that stupid little talking lion.  It made me mad to no end.  The flute dagger was way better than lion dagger

I watched the original back in the day and never really followed what happened after that. lol, I used to argue with kids at school about who was the strongest.

If I had to guess now I would go with the giant blue dog samurai power ranger. Oh Japan, you so crazy.

I only watched the first few series, but the original was the best of those that I watched. Only while the Green Ranger was evil though. The evil Green Ranger was a badass.
