Schmaltzy fantasy/romance about a kid who wishes to be big (hence the title). His wish is granted, but his mom thinks he's a burglar and as a 13-year-old, he's not really equipped to deal with the adult world. At least, that's what he thinks, as this is the type of film that twists things around until they fit the moral of the story.
I've never liked Tom Hanks much, his role as an annoying manchild here won't do much to change that. The only good thing is that they didn't cast Robin Williams for the part. Hanks' romantic interest is pretty dull too, as is the rest of the cast to be honest. Then again, it wouldn't be fair to blame everything on them.
It's no surprise almost everyone in this "always keep your childlike wonder" tale falls for the charm of Hanks, I can't say I could really go along with that. Marshall's bland direction is definitely a reason, so is the languid plot, the poor casting and the drab styling. Hollywood cheese with few redeeming qualities.
