I did watch the first Hotel Transylvania on theater. I really did like the physical/screwball comedy and animation, the art designs and the cutie known as Mavis, but much of the other comedy was hit-or-miss, it had some of the annoying cliches that plague a considerable number of modern animated movies and I felt Genddy Tartakovsky would have done much better things with the direction but the executives enforced him to follow strict rules that lead to the cliches seen. Don't get me wrong, I liked it but it wasn't very special, though I did watch it dubbed in Spanish, so maybe it could be a bit better in english.
I would have watched the second by now, but it's only avaiable dubbed on every theater.
