Just a quick review, so apologies if it is badly written - I just finished watching this and loved it. It really is fantastic! I was impressed by 'Under the Red Hood' and its more mature style, 'Apocalypse' continues in this more style, lets hope WB keep it up.
WB has finally realised they need to spend some money on the animation and it really shows here. The animation makes 'Doomsday' animation look childish. Some of the direction is what I would expect to see in a live action movie, great camera angles etc. Many of the fights looked motion captured, there was something very fluid, realistic and believable about them.
Music wise, it is good, but nothing really memorable, you wont find yourself humming at work the next day...it does the job and fits well.

Admittedly, the storyline is a little basic, but enough to keep any fan happy. It's mainly about the arrival of Kara, and is more based around Superman than Batman, though Bats is there doing his usual stuff its not really about him (or Wonder Woman).
The final battle is on the Kent farm and is somewhat unexpected, I think this battle tops off the movie almost bringing it up to 5 stars for me. I could have watched the entire battle again, tattered clothes 'S' shield showing through...you know Kal El mean business, and Kara too! Truly the best battle in any WB movie I have seen to date.
Lets hope 'Man of Steel' in 2011 is something like this!
If you are a Batman / Superman fan then you have to see this. So far it is the best I've seen.
