I don't think it's as funny as when it first started, although still amusing. There are some parts of it that are done in a bit of bad taste, although I'm sure it's supposed to be funny.
It's still pretty funny, but definitly not as strong as it use to be, took the same path as The Simpsons, but alot faster.
the Simpsons can still be really fucking funny if you catch the right episodes I wouldn't say the same about Family Guy ever since it was brought back, it just sucks =/
