Power Rangers Samurai
The series is a franchise "reboot" after Saban Brands reclaimed the rights to Power Rangers from Disney.

Why Change It?
Power Rangers Samurai is one of the rare examples of a faithful adaptation to the source material being the wrong solution. In the past, this practice worked in Time Force and Wild Force, but the main problem is that Samurai Sentai Shinkenger is culturally impossible to directly port over into a western environment. The premise of a Samurai lord and his vassals works in a Japanese show, but with Americans, it doesn't make sense. In addition, character traits in Shinkenger were very crucial to many storylines. For example, Ryunosuke's background as a kabuki actor was invaluable in foiling Dayuu's bride-kidnapping scheme. Kevin's background as an Olympic swimmer has nothing to do with the series; as a result, the PR Samurai version of the bride-kidnapping episode lost its punchline.

Oh yeah, did I mention that these people can't act their way out of a paper bag?

What Would I Change?
The first thing I'd change would be the most obvious: the actors. Get people who can actually act instead of just standing there and reading the cue cards, hoping no one would notice.

Second, just make a completely different story. Instead of them having their powers handed down from past generations (which doesn't make sense, given that they're not Japanese), just have them stumble into a cave and find ancient relics that give them their powers. That always works, doesn't it?

And lastly, drop Bulk. Sure, he was added to the series for nostalgia's sake, but he's nothing but episode filler, and Spike is no Skull.
