Aggressive Retsuko Season 4, was not as good as i expected to be, it was not bad either but did not live up to its Hype. Season 1, 2 and 3 did great but IMO season 4 is the worst out of all of them, reason being is it kinda loses its touch, and the fact that retsuko is not really focused on as much makes it lose its charm, at the same time, I wanted to see more of Retsuko death metal singing. The story itself is not too bad, but I find sometimes shows can go past their sell date, meaning they keepadding seasons, but the show starts to lose its charm. The show it self with all seasons included is an 8.5, but this season is a 6.5 hence that is why i rounded the score to 7.

If you watched all 3 seasons of the show, I would still say check out season 4 as well.
