We took both DS's (6 & 4) a couple of weeks ago to see tangled. They liked it, but DS1 really wants to see Yogi Bear and I think he will like that more.
I don't want to be stereotypical, but I think he'll like Yogi Bear better because it seems more boyish than Tangled IYKWIM.
I'm sure though that your DS will enjoy either!
DSS 13yr, DS1 4yr, DS2 3yr
