Preliminary (3/? eps)

Ok, so I wouldn’t normally leave a review this early, since I prefer allowing things to marinate a bit before forming opinions worth sharing when it comes to reviews.

BUT …

It was made abundantly clear to me within moments of viewing that the once established spirit and mood of tensura that existed in previous seasons is actively being reprised here, and this is something we needed to see in respite of last seasons complaints.

The massive roster of producers beneath this have certainly fixed some bugs this season and polished the show’s already charming design. The enhancement is quite notable.

The worst part is that it shows moments where it *could* do something genius, but instead it says, "screw that, here's more slop".
