I gave it a 5 because I think a show or movie starts at five. From there it either goes up or down.
On the down side this is the cheap Flash animation style that Teen Titans Go uses. Rainbow has no sense of self preservation. Sh sounds like a 45 executive trying to be an 8 year old by spouting every buzz word in the book. There is never really a time to reflect on what you just watched. This is fast fluff.
On the positive the animation is decent. The colors and character models are very reminiscent to the originals. To me though, the limbs look and movements more stretched out like an early teen.
If you want a poor man's version of My Little Pony this is for you. Nothing really offensive but now real substance. BTW: Rainbow Brite is the equivalent of Pinky Pie in the current MLP.
