Saw this in the cinema (accidentally)

But enjoyed it - more than I expected to once I realised my mistake. Just watched it at home and, apart from Vanessa Kirby and a brief bit of Eddie Marsan, it's distinctly meh! Run of the mill silliness with ridiculous special effects, some meaningless guest star pop-ups and an unconvincing attempt at a sentimental end.
Which I guess makes it a big screen film?
