"Streetdance" in 3D.
To my surprise, I quite enjoyed it. I thought the dance scenes in 3D worked well, as did the views of London. The 3D isn't in yer face & over the top, in the way that I've found irritating before.
Low budget, the plot isn't exactly sophisticated, & some of the lead performers are obviously better at dancing than acting. But then . . . they're not called upon to act outside themselves, so that works, in general. And there's Charlotte Rampling, for nostalgia.
