Anytime something good has happened for any one of them it has been undone by their own actions, cruelly revealed to be a dream, hallucination, overdose on booze, or otherwise ended poorly. The gang of Charlie, Dennis, Dee, Mac, and Frank (played by Danny DeVito who joined in the 2nd season) has always surprised viewers here-and-there with little funny twists or turns, but the whole point has always been that these are terrible, horrible people who are doomed by their own hubris to be miserable. 'It's Always Sunny in Philadelphia,' has been running for 13 seasons now, with the finale for season 13 airing last night.
