Can fans experience the gleefully dark comedy of It’s Always Sunny In Philadelphia on Netflix? It’s Always Sunny In Philadelphia debuted on FX in 2005 and follows a group of friends working at Paddy’s Pub. It may be a sitcom but there’s nothing light or fluffy about it, with the gang - consisting of twins Dennis and Dee, Mac, and Charlie - being horrible, amoral creeps. The first season received good reviews but weak ratings, but the show became way more popular following the introduction of Danny DeVito (Jumanji: The Next Level) as Dennis and Dee’s equally horrid father Frank.

It’s Always Sunny In Philadelphia has gone from strength to strength ever since, with the Paddy’s Pub gang getting caught up in any number of evil schemes that usually end badly. The group also refuse to grow as people, with Charlie still pining after the unnamed Waitress (Mary Elizabeth Ellis, Santa Clarita Diet) after years of stalking and rejection. Despite their frequent cruel actions, there’s something strangely likable about the group, which is down to the talent of the performers.

There was some concern over the future of It’s Always Sunny In Philadelphia when Dennis appeared to leave at the end of season 12 to raise his child. In reality, star Glenn Howerton left to work on NBC sitcom A.P. Bio and it wasn’t known if he would return for season 13. The team behind the show played up this mystery, only revealing Dennis’ return at the end of season 13’s premiere episode; Howerton would ultimately appear in six of that season’s episodes.

It’s Always Sunny In Philadelphia season 13 received solid reviews on the whole but wasn’t considered the show’s best. That said, it’s finale “Mac Finds His Pride” received acclaim. For most of the series, it was an open secret Mac (Rob McElhenney) was a closeted gay man, though he finally accepted this in season 11. The season 13 finale found him struggling to tell his convict father, so at the end of the episode, he performs an elaborate dance to express his feelings. His father still rejects him, but the dance was a genuinely moving sequence for It’s Always Sunny In Philadelphia, a show that typically wallows in darkness and despair, and even moved Frank to tears.
