I saw Van Helsing yesterday, and i gotta say that besides the scary monsters in it, it was childish, and bled from thousand bugs. At the end, i held my head with both of my hands because it literally created an impossible scene.
I think the LEGO movie can be much better than Van Helsing, because it will not concentrate on fancy CGI, and scary but illogical stereotypes, but it will focus on good jokes and funny moments.
The visuals really shouldnt matter that much when you watch a movie.
