I watched it for only one thing....

Rating: 7/10 (7 June 2015)

I went to go see this movie because I'm a bit of a World War II nerd.
So my main focus was simply seeing the Tiger tank (a real one, and unless I'm mistaken it is the only remaining operational German Tiger in existence) in action. Truly frightening!
I did like that tank battle because it did display authentic tactics, and serves to remind us of a handful of things about armor engagements in that war. Two primary accurate things were: 1) Those tanks move slow, compared to today's versions. 2) At the least, allied tank units quickly developed a preferred operating procedure of needing at least 3 Sherman's to 1 Tiger (if not more) to overcome the Tiger. And they did it pretty much to code - get one Sherman behind the Tiger where it is weakest.
When you see the beginning of that engagement, the three Shermans are not widely dispersed. You see that as they get closer, they start to spread apart. But you also have to remember that over rough terrain, they're probably moving at the blistering speed of maybe 5 miles per hour.
I found that scene both frightening and exhilarating all at once.
So beyond that, I found I enjoyed most of the movie. The scene in the town (early on) and the interaction with War Daddy and the FNG (er, new guy) with the two female residents ran the gamut of "this is a good scene" (it was) with a heavy dose of "why are the other crew members being such jerks" (to put it mildly).
And the crew is justified on being hard on the new guy, given the story we're told. That crew, before losing their assistant driver, had been together quite awhile. Not only have they lost a brother in arms, but now they have a new guy that they don't know how well he may or may not do. And that is amplified by our new guy pulling a Dante (from Clerks) reminding them early and often that "he wasn't supposed to be here".
However, some of the harshness, nigh cruelty, just doesn't really do much for the story. Sure, there are points where they sort-of warm up to him, which to me only served to highlight their earlier useless behavior.
One note - Shia LaBouff's character (forgive me if I spelled his name wrong) was much better than I was expecting, given the articles I had read about him during it's making. I'm not much on 'method' actors, but his character was mostly more likable than I would have anticipated.
Overall, don't look for accuracy. I could go on about damage done by a grenade inside a tank being COMPLETELY overlooked for the sake of the movie (ahem, instead of people almost dead, at best you MIGHT have someone almost alive) but then this isn't a documentary or a training film - it's a movie.
You can enjoy this movie.
