I have often debated on this blog whether a show should continue once its original premise has been fulfilled. Revenge seemed to be resolved enough after season 3 to make a fourth unnecessary, with plotlines truly jumping the shark. Ditto Once Upon A Time, which must surely be running out of ways to make Regina and Mr Gold evil On the other hand, Grimm has managed to make the season 5 story arc last long enough to go into season 6, although I still feel its swan song is approaching.

So where does that leave Suits now that Mike has been found guilty of legal fraud and is serving time for it? Now, I have to admit to bias here, as Suits is genuinely one of the shows that I genuinely love and spend a lot of time breathlessly talking about to others. So naturally I want it to continue, but only whilst there is enough breath in its body for it not to need life support.

In my opinion, it is doing surprisingly well. I initially found the prison scenes a distraction from the glamour of the law firm, but the espionage and counter-espionage is as present there as in the courtroom. Any thoughts that there would be no place left for tension can be banished, as Mike must both stay out of trouble and land someone else in it, whilst battling loyalties.

I find Pearson Specter Litt as fascinating as before, despite it being wounded. Most shows would have had Harvey strike out on his own and focus solely on helping Mike and building his own firm from the ground up, but The Good Wife stole the march on the virtuous rebuild, so instead we see Harvey, Jessica and Louis going into battle together. Jessica had always been a bit too much of an ice queen compared to say, Donna, but this season has shown a vulnerable streak, yet one that isn’t so much a chink of her armour but instead one that is an extra weapon. Her flip reverse on the pro bono idea of Rachel’s was a good example of this. It was also a relief, as I still find Rachel the most frustrating character, so desperate to be independent and sassy, yet so in the shadow of everyone around her.

So yes, Suits is pulling off that rare trick of going beyond its brief but still working. Perhaps that’s because it has always been slowly building to being more than the Mike and Harvey show. Even if it has sometimes relegated the other characters, it has never dismissed them completely, and each has had moments to shine. One day, of course, it will stop, and I will miss it. But like those that come out of a mid-life crisis energised as opposed to obliterated, Suits is extending its lifespan through canny plotlines and a smart recentering of the action.
