Soul Eater NOT! is pretty much what it sounds like... not soul eater XD If you go into it expecting Soul Eater you are gonna be disappointed but otherwise the first episode wasn't terrible and I did enjoy seeing the old characters and the little fight scene was pretty tight. But it does really suck that they changed the animation style from the original... I mean it's like night and day, check it out.
I mean look at that shit, it's a bit unnerving that the did away with the awesome comic book esque animation / art style of the original series which is one of the reasons it was so awesome, but I understand this is a spinoff targeted at a totally different audience which is why they chose to go with a more clean and up to date modern art / animation style. With that said their really isn't anything wrong with the new style, it's clean and looks great but I suspect fans of the first series will probably be cringing every single time they see the old characters in this new style. I know I cringed the first time I saw Maka in this first episode, she was just too moe for me (which is something I never thought I would say about any character). I miss that blank lifeless stare so much
