After seeing 'Dark Shadows', it's easy to see why 1313 ML fails.
The 2012 "Dark Shadows" movie does a lot of similar things, in digging up an old property, innovating on it, while remaining true to its roots.
Both use dark humor and shamelessly killing.
If 1313ML had someone with the deftness of Tim Burton, it might have succeeded.
1313ML feels very heavyhanded, while the 2012 "Dark Shadows" movie felt more natural.
That might be the difference...
