[conundrum]

As for the PG-13 rating, it would be easy for the film to get that. Just show Tommy a little beat up/bloody or have some really intense battles with big explosions. Heck, the tiniest bit of swearing will do it.

I can see it working and be a success, but it'll be like transformers where kids love it and most fans loathe it.

Want to know my plot?

A new alien threat is discovered. To combat it, a secret government organization extracts the Dragonzord from Angel Grove Harbor (where it should still technically be). They reverse engineer the ranger powers from it, tapping into the morphing grid, and assemble a new team of 5 core rangers, however, they are inexperienced and unfamiliar with the equipment. Desperate and with armageddon fast approaching, they turn to Tommy, the only man capable of training and mentoring this new team. Tommy initally dislikes the new team because he's comparing them to the original, his friends. He disbands and tries to take on a large group of monsters on his own but he starts to get his ass handed to him and is about to be killed when the new team shows up saves him, gaining his respect. In the end, Tommy would sacrifice his powers/zord to stop the threat but state that the world doesn't need him when it has the new team. An end-credits scene shows the research/develop team secretly working on something. Zoom in on the white ranger logo, panning out to reveal a modernized saba and parts of a white ranger suit as people bustle around. Bam.

Simple, but it would reintroduce the already rich mythos of mmpr and open it up for further sequels.
