There are a lot of skipped parts in Tazza: The Beelzebub's Song.

It follows the original manga story, but
it spends about 1 hour and 30 minutes just on the early parts,
and then skips through most of the revenge arc afterward,
which makes the revenge feel very bland.
Still, it's decent enough to watch a couple of times.
In the Tazza movie series, Part 1 is on another level, Part 2 is decent, Part 4 is for killing time, and there are 3 total flops...
I feel like Tazza 4 would have been better if they had filmed it as a drama following the original manga content without any adaptations, maybe around 8 episodes.
