Monsters Return in 'Hotel Transylvania 2' Trailer

It's the week of animated movie trailers, apparently. Adam Sandler's Count Dracula is back in Sony's sequel to the popular Hotel Transylvania three years ago, and now they're trying to convert his possibly human grandchild to the join the "right" side of the family. This is another release coming out in September, although wouldn't it be more appropriate for an October release, closer to Halloween? You know, with there being so many monsters and vamps and all.
