The stuff with Hughie's father was one of the stronger parts of the show though. It may have been a side story but I thought it was really well done.I dont think it was horrible or anything, had some great moments for sure. And I think the finale has set up the final season extremely well.
But I also felt like quite a bit of filler occurred this season that didn't really add much value to the season so far(Hughie's father, Deeps Love Triangle, Noir talking at all).
Overall a solid like 7.5/10 for me, but I'd probably have the other seasons all in the 8.5-9/10 range I think.
