So my summer blockbuster viewing, which got off to a disappointing start with Spider-Man 3 and 28 Weeks Later, went slightly better this afternoon with Shrek the Third. It’s genuinely cute and sort of amusing, and even if it isn’t those things all of the time — and is, more often than not, sort of tedious, really — overall it’s pretty harmless. Faint praise, maybe, but I don’t think I was expecting much more going in.
