Four egocentric friends who run a neighborhood Irish pub in Philadelphia try to find their way through the adult world of work and relationships. Unfortunately, their warped views and precarious judgments often lead them to trouble, creating a myriad of uncomfortable situations that usually only get worse before they get better.
I'm sure Dennis would say this show "hasn't even begun to peak yet", but I think it did a long time ago. I find season 3 and 5 to be the best of them with the highest number of amazing episodes and the least forgettable ones. Season 4 isn't too far behind. It must be mentioned though, that that is when I got into the show. By chance I caught an episode on TV, got all of the episodes and binged season 1-5 and then I've watched 6 to the current seasons as they've aired. While on my rewatches, I don't find season 7 to be as bad as I used to. I do think that's when the ideas started to fall away. There are some episodes in season 7 that don't do much for me. Much of the humour in 'Frank's Pretty Woman' and 'The Gang Goes to the Jersey Shore' is just shock humour - think the vomiting blood capsules scene - and 'Frank's Brother' is one of the worst episode from the series (competing with 'McPoyle vs. Ponderosa: The Trial of the Century' from season 11). 'How Mac Got Fat' is decent but is put together from an unaired episode. The final double episode of 'The High School Reunion' is a letdown as well. So, despite having some strong points like 'Thunder Gun Express' ("One of the things I like doing most is banging whores"), it has many more issues than what preceded it.
I must note though, that from what I've seen online, the above isn't a common opinion. Many love 'The Gang Goes to the Jersey Shore'. From there, I think season 8 was an improvement in consistency. They began to include many more call-backs, including the fun 'The Gang Recycles Their Trash' episode. Again though, the poor moments like 'Charlie Rules the World' are a lot worse than what we have from the earlier seasons. I won't review every season now, but the other issues on occasions have been the consistency of character. At times Mac in particular has been inconsistent with how he interacts with Dennis. From not listening to a word he says to acting like his puppy.
Many of the show's greatest episodes, like 'Mac Bangs Dennis' Mum, 'Kitten Mittens' and so on, have the gang break off into pairs or a triad and then come together for the episodes' conclusion. That structure seems to have become less common, as did the bar as the episodes' setting.
A little bit like The Simpsons, it isn't as consistent and amazing as it used to be, but for its peak, this show is a must watch.
