I'd give this mixed if I could, but I lean towards positives.
This is very much so a low budget fighting game and you can tell from how some earlier characters look and feel to play compared to characters like RJ or the SF5 crossover characters. Not like it isn't fun to play any earlier characters, I still love playing Slayer and Dragon Yellow, but they noticeably have less sauce to their visuals and flatter sound effects. If you prefer movesets and feel to visuals, you won't mind it at all though.
If you're into single player content, steer clear. Story mode is a bunch of versus fights and not much else, and if you're playing it for the story, getting the source material (Shattered Grid comics) is more worthwhile. Ai kinda sucks, but that's an eventual given when you learn how to play the game, no AI that I can think of is actively going to mess with someone who can do advanced techniques in a game.
I also gotta mark it down for the BBTAG syndrome of having a majority of the roster be DLC, but it's no SF5.
Despite all that, the amount of cool stuff you can do with characters in this game wasn't expected at all, I thought this would be a really beginner oriented game but it's got tons of stuff for people who *know* fighting games. It's still beginner friendly, but the skill ceiling is high. That's the main reason this is positive.

TLDR: You like story or flashy visuals? This ain't it. You prefer how the game plays? Chip in.

One of the best.

I love power rangers and fighting games. this is awesome sauce
