Soul Eater is a mix of horror, action and comedy. It's not really scary, but the horror/Halloween themes make it fun to watch around October. However, it excels in the last two; Soul, Maka, Black Star, Death the Kid, Crona and Tsubaki all deliver crowning moments of funny, heartwarming and awesome over the course of the series (Don't care much for the Thompson sisters tbh), and that's just the main cast!
The animation is great to look at, the music is fitting, the plot is very well-paced (Despite the series being 51 episodes; honestly, I feel very few shows deserve to be longer than 26 episodes, but this is one of them) and original, the characters are all well-written and likable, and so on.
Some people didn't like the gecko ending, but let me just point out here that if you know what it is, the actual scene isn't as stupid as many people make it out to be; hearing what happens and seeing the episode complete with all the buildup aren't the same thing. I personally liked the ending, but I guess I'm in the minority here.
To anyone here who is a fan of FMA (Probably 95% of the readers), this show will probably appeal to you a lot. After all, this is pretty much FMA's spiritual successor. Well, since FMA is only my favorite anime/manga series ever, here are a few of the similarities in particular I'd like to point out:
-The place Maka enters within Soul's mind at one point REALLY resembles the gate from FMA
-Both of the main characters are blond-haired and get angered easily when someone points out how underdeveloped they are
-when a certain villain fades away it really resembles when the homunculi fade away
Overall I'd give Soul Eater an 8.5/10. It's no FMA or Trigun, but with the great characters, a fun setting, and overall awesomeness, I can safely say Soul Eater is the one story I wish I could have written. I don't favor it over the aforementioned masterpieces FMA or Trigun, but if someone asked me if I could just magically make myself the author of any anime/manga series, I'd go with this one. I'm not quite sure why myself; perhaps its the horror elements and the fact that I'm obsessed with horror films? I don't know, this story just REALLY appeals to me.
I haven't read the manga all the way through yet (I'm about 10 volumes through, though I guess I'll review it when I'm done.
