Spoiler-less, TL;DR, fast, simple, and easy-to-digest review:
Summer-y, Delightful, Family
8/10
Animation? Good (++)
Same as the previous season. It is good but not the best.
Characters? Ok (+)
Great range of characters... except for one. I detest that character the most!
Story? Good (++)
A worthy sequel but not better than the previous season. There are some filler moments and hate-able moments that you want to reach the screen and scream at them, but still good.
Pacing? Ok (+)
Bearable mostly. Slow burn as always... but this time, the payoff is way less than expected. Need to watch the next season to fulfill that itch.
OST? Excellent (+++)
Ah, the same as the previous one. A great encore to the original ones!
Enjoyability? Ok (+)
While some viewers may not enjoy some episodes, at least some other episodes outweighed some bland ones.
