I will say tho, 2nd and 3rd season have better quality than the 1st especially in animation quality. With that being said they use a couple of animation sequences from the original anime here especially with sayaka. Music are pretty good but not even close to the original. Also, the ambience and atmosphere is much better than the season 1, but again not on par with the original. There are some loose plot points but if you can ignore it i say you give it a go, especially if youre still on the fence on watching the entire series. And the story of iroha little sisters also prettytragic and she turns into something pretty grotesque, so if youre into that definitely watch it.
