There's nothing really here. Looks like the director was trying to work through something about having a depressed mother and thought: if only I could go back and play with her when she was a child. But it turns out not to be a good way to work through the problem, at least not with the child mother as thinly imagined as here. It's also not clear, at least to this audience member, that the problem is all that big a deal.
The result is a very dull movie indeed.
