"Journey 2: The Mysterious Island" looks like nothing so much as one of those live-action adventures that Disney used to grind out in the 1950s — and hey, here’s Captain Nemo’s Nautilus to prove it. Also, a tree house to humble "Swiss Family Robinson, " which contains a short-wave radio that has been assembled from old spoons, I think I heard.
This is transcendently goofy. It isn’t a "good" movie in the usual sense(or most senses), but it is jolly and good-natured, and Michael Caine and Dwayne Johnson are among the most likable of actors. Johnson is such a good sport, he even shows young Sean how to impress girls by flexing your pecs so quickly that nuts will ricochet off them. I can’t think of any reason to pay extra for the 3-D.
