The three comedies made by writer/director Edgar Wright and stars Simon Pegg & Nick Frost — “Shaun of the Dead,” “Hot Fuzz,” and “The World’s End” — have become collectively known as The Cornetto Trilogy and Universal has been collectively smart enough to release them in one edition, complete with Ultraviolet versions of each beloved film. “The World’s End” is also newly available on Blu-ray and DVD, sure to find legions of loyal fans this holiday season. I like but don’t love “End,” finding it the least satisying of the three films but consider that criticism as coming from someone who adores both “Shaun” and “Fuzz.” There’s still a lot to like here, especially if you want to buy all three.
