In my own opinion Family Guy is not like it was, not too long ago. I mean Family Guy used to give its viewers relatable comedy or fresh comedic comedy through there story lines, cut-aways, and even the characters throughout the series, but recently Family Guy's newer episodes seem to have bland cut-aways or story lines that are completely unnecessary.
Heres how the years have been: (Ratings Wise)
Season 1: Not Bad
Season 2: Ok
Season 3: Kinda Funny
Season 4: Hahaha Getting funny!
Season 5: This is really funny!
Season 6: Hilarious
Season 7: Still Go It, Funny
Season 8: A favorite
Season 9 Ok, Still kinda funny, ehh
Season 10(2011-2012): So many flat and overused jokes.
Season 11(2012-2013): Ok, OMG Unnecessary plots, flat jokes, Half funny episodes.
