To beat fire, USE BIGGER FIRE.
Lets me be honest, I can never get hooked with this anime. Mainly because I no longer enjoy mediocre shounen that designed for young teenager without having any other strength. This 2nd season is good, but i still cant hooked with it (determined by I either care about the story while watching it)
That said, this is 2nd season of anime that I didnt give good score on 1st season because of several issues that I felt missed potential. The anime studio is David Production (JOJO!!!), so you can be sure that production will be really good. The story is getting more interesting as the team discover some big revelation about religion in their world. They also trying to get their hand on powerful human who can wield unique fire ability, preventing from the villain getting their hand on that human first.
As for my problem with the anime, i would say that this anime is still fail to play around with emotion. While there are still hype around how extreme beautiful the combat, the slow section is always reserved for lame joke from various characters that i feel cringey. Tons of times are spent babbling about info exposition related to their power, their world, their religion, their history etc. Despite several deaths in the series, there is no sad or part that truly felt tragic unlike most modern shounen.
Should you watch the anime now it have 48 episodes? It is depend, the anime production quality is there, but i dunno if i can justify better season 2 when it required you to watch 1st season as well.
There will be no alternative for any for sequel anime review in the future.
