TLDR
This show isn't without its flaws, and if you're not into Isekai this won't convert you. It is, however, fun with a (mostly) likable protagnoist, a slightly different spin and a silly plot that rarely takes itself too seriously.
Further thoughts
Mitsuha is the protagonist. She's a go-getter, likable but somewhat mercenary in her convictions. While there is a fun supporting cast don't expect any found family stuff, despite the premise. She's looking out for herself mostly. This isn't a negative, but it is worth considering if you like the found family stuff.
There's no real world building here and the final arc comes out of no-where. Again, these aren't negatives for me but it all leads to a final confrontation which is magnificently stupid. I loved it, but it is the peak of ridiculousness. If you want a deep and compelling story this really isn't the show for you.
Honestly if you want to follow a compelling, but not angelic, protagonist with a few fun side characters this is for you. It is, by no means, a must watch but it's a fun way to kill time if you like your Isekai.
