Family Guy, to me, is like that giant bag of junk food you know you shouldn't touch, but occasionally, you need a fix. I like the show, but it's a true guilty pleasure, because I know I could be watching better stuff I know nothing about yet.
STILL, Family Guy -- while 99.9% unoriginal since Episode 1 -- can belt out a good episode once a season or two. This happened with their alternate universe episode (like i said, not original at all.) The producer of that episode did a great job on the one part where they were in the D****y universe.
Very faint praise at best, but I give in to Family Guy at points. I know, I know.
