Probably the best thing about Hell is that it shows how The Road would turn out without the media frenzy: almost unnoticed and scoring averagely on IMDb. This might not be the best way to start the review, yet as the movie progresses one starts wondering whether Hell's authors could have chosen a different path. Either way, the result is a straightforward post-apocalyptic thriller.
The advantage of not having a major studio in the background is the absence of pretentiousness. If you're into such movies, you'll like it. If not, you won't go to see it in the first place. In my opinion, this only adds to Hell's artistic merit.
I can't tell whether the title (meaning bright in German) is a wordplay on purpose or a slip of a tongue, but this is a pleasant surprise for a German-Swiss production.
