Thanks Chris for your comments.
It doesn't surprise me that much, there was to much packaging/marketing around
this film, we've
already seen that with other films (Gigabitfilm, ...).
I'm afraid we'll encounter other "marvels" like this one in the near future as
the giants are slowly
leaving the place ...
