Seeing that ARMS follows the Splatoon mold and comes with free updates down the line the most prominent complaint of 'lack of content' doesn't worry me in the slightest.
I get that reviewers have to work with whats there and cant really speculate on future updates but this and Splatoon are some of the rare cases where adjusted review scores would make sense in a positive way. (Loads of games would actually need to be adjusted down because of retroactively patched in microtransaction bs.)
But yeah, this seems like a decent enough score for what it is and game reviewers tend to be a bit confused by brand new concepts anyway. I'm pretty sure that Splatoon 2 will score significantly better than Splatoon even if it only offers incremental imrovements on the core gameplay.
The best reviewed games tend to be the ones that improve and refine upon well tread and familiar territory like TLOU and BOTW. Both games don't actually do anything that hasn't been done before, at least in concept, but they refine it to perfection, hence great scores.
