The Ghostbusters said you should never cross the streams, but Disney had massive success when its animation division adapted a little-known Marvel comic. As in many classic Disney animations, the plot is driven by the tragic death of a parent, but what Bambi and The Lion King lacked in robots and sci-fi action, Big Hero 6 delivers in spades. The San Fransokyo setting is a wonderfully inventive fusion of East and West, while inflatable robot Baymax instantly earned himself a place alongside R2-D2 and WALL-E in the pantheon of all-time great droids. And yes, even though you have to keep your eyes peeled to spot it, the regulation Stan Lee cameo is all present and correct.
