Day was shit, that I will agree. The Snyder Dawn remake is not my favorite but I wouldn't say that it sucked donkey balls. A remake should be distinct from the original, and Snyder took the central premise and took it in a different direction relatively well, which I appreciate. He also seemed to show respect to the original and to Romero without being slavishly derivative. Snyder has a narrow window of talent in terms of his style, but he makes it work well enough to create an entertaining film. Oh, and the opening up to the car crash is really nice, it is my favorite part of the film.
I really don't like fast zombies or disposable one-note characters so the film doesn't gain much of a favor from me. The over-emphasis on action is another sore point, and I think it really needs a bit more down-time to let the characters and the situation breathe and really impact the viewer. There is also a lot of really stupid decisions from the cast to produce a lot of drama/action scenes that felt really forced and contrived, as opposed to the more grounded motivations of the original.
If you like Snyder's Dawn or dislike it I think that comes down to you and your feelings, but I don't think its necessarily a bad film in isolation but maybe a bad remake of the original.
You would like the remake. Go watch it right now dude.
