My we have a lot of people who've only been watching Magical Girl animes here :/
I've seen Vexille, and I can assure you it had no silly magic and was in fact a mech, so there was pretty much no magic to be seen anywhere, unless you consider nanobots magical.
The animation wasn't great I'll admit, but it was pretty decent.
I don't know exactly how to judge this, on the one hand I'm excited that there's a DA film in the works, on the other hand I've never seen a decent game-to-film adaption to date (nor the reverse), so if anything it'll be a good film in its own right, but will be raged at by fans by not being good enough, accurate enough, exactly how they imagined it or any combination thereof.
Here's a novel idea; let's see a proper trailer before we shoot it down in flames...?
Speaking of flames *raises her firewall*
