What I Liked: Brilliant and creative animation style, great character designs. Interesting use of Christian mythology. Nice soundtrack. Great voice acting from Linne's VA.
What I Didn't: Could've been about 30 minutes shorter. Interesting use of Christian mythology. Strange pop culture references clashed with the story. Animation occasionally suffered from quality issues. The plot switches from positive to negative faster than a kid playing with a light switch, and it's distracting as all get-out.
Final Verdict: Hells is quite an interesting little piece about self-confidence and the power of positivity wrapped up in an artsy little bundle. It's not absolutely amazing nor is it ground-breaking stuff, but it's a good way to spend an afternoon.
