Attack On Titan (or Shingeki no Kyojin) is enjoyable, despite having quite a few issues:

Plot, plot, plot! It's paced choppy! Characters! Characters so troupe-based that it hurts. I'm looking at our edgy protag whom only speaks through his teeth. Get over yourself, Jaeger. Really...the only characters /truly/ worth any screen-time are the background characters (Sasha, Annie, Connie, etc...) Cliches. "little-girl-who's-probably-not-even-13-yet-is-able-to-easily-kill-a-man-without-breaking-down-and-freaking-out-bc-he-killed-her-parents" cliche. Another con: Bryce Papenbrook. I'm so sorry, I absolutely HATE actor-shaming but I have seen him voice so many teenagers with edgy-issues (Shirou Emiya, Kirito, Eren, etc...) that it now makes my ears bleed. Half of his lines are SCREAMING that "I will kill all the titans! I'm ten ft tall even tho im rlly like 5'7, lmao!!" The english dub is OK. that's it. If you want a good english dub, see Fate/Zero.

Here are some good things: The !! Directing !! Is !! Beautiful !! The concept is wonderfully amazing and fulfilling! I love post-apocalyptic plots! Most of the characters are tolerable, if not lovable. Comedic moments are well placed and paced. They don't pop in at random moments like in other anime's (SAO, Naruto, Fate/Stay Night...) The animation is surprisingly good! I love it and its beautiful. THE GORE IS SURPRISINGLY GORE-Y WITHOUT BEING COMPLETELY GROSS AND GROTESQUE (with that being said, I would be fine if they showed some eyeballs and internal organs, lol. Corpse Party had me wanting more.) YES ALSO THE SOUNDTRACK IS THE /BEST/ thanks for coming to my ted talk bye bye
