My son is turning 4 and is Spiderman crazy. I want to buy him a boxset of a complete Spidey series. But which one to get? He has a few DVDs of the 2002 series (Spidey vs Doc Ock, Return of Green Goblin, Ultimate Villain showdown). That boxset / series seems rather expensive. I'm inclined towards the 1967 set but would he like that? Otherwise, which series to get?
