This movie is...bad :/
First and foremost the voice acting in this movie is really bad. I kid you not. I thought All star was bad but man this is horrible. Almost all character voices are bad. The only redeeming ones would be Alfred, Talia and Rebecca (daughter of the Doc Langstrom). Batman comes in at just barely ok. There isn't much life in the voice acting and when there are they seem to be out of place. This I believe must be the problem of the director. They are not meshed altogether well at all.
Secondly this movie has tons of smart-ass, dumb, one liners and cliches. The beginning part with Talia and Batman was cringe-worthy bad and shameful. So bad I didn't even find it funny but had to turn my head and sigh a big Urgh. I warn you, there are are way too many.
Now to some more of the bad although not as bad as the first two. The animation is a hit or miss depending on the scenes. The fight scenes are the same. The fight scene with Damiam and Ubu was bad and worse when they showed the scene immediately where Nightwing comes in. The scene had Nightwing posing for a few seconds after knocking Damian down on his high horse. This was so stupid I couldn't even laugh at it. They had him catching and holding up the katana like some King Arthur scene. Utter ridiculous. Sometimes you have characters just standing there waiting, in what appears to be surprise, for their imminent death. It's stupid. The slow motion used was acceptable but really not up to standard.
Music is uninspiring to say the least. There are parts that the music just seems out of place, not matching the destruction of the scenes at all. Character designs changes from US style (I guess you can call it that) to almost Anime type. This is a bad thing but it is inconsistent.
The direction where DC is going with the New 52 is not inspiring. It really does not help when they don't select the right voice actors for the roles. I can deal with Sup and Wonder Woman getting it on but this voice acting has got to STOP!
Watch it because you love DC but be forewarn of the dangers.
