I enjoy that they let hitting be hitting mostly in the playoffs. Calls like charging, boarding, hits to the head, etc. are all called pretty well and fairly come playoffs and 99% of the time they get it right. Now as for all of the stick work it's horrendously inconsistent. It goes from being called all of the time to "well did it lead to a scoring chance and is the game even close at this point?" type questioning and it's nonsense. It just leads to resentment with the officiating because they'll let one team get away with murder and the other team may have a reason to play it safer so the team constantly interfering, hooking, etc. all get an added advantage and it makes the playing field uneven.
Just call it and call it both ways.
And not to mention the times where they decided not to call it and go, "Oh man that was a penalty but it didn't fit the narrative of affecting the game like it leading to a scoring chance or something so now I can't call anything because we just set a standard of not calling obvious stuff now" or "It's the third period, can't be a loose with the whistles as we were in the first"... It's so bad.
And cross-checking. It went from at times being something where you actually had to earn the call by forcefully putting your stick into somebody to even brushing your stick up against somebody horizontally is now a penalty. Nobody likes the weak calls, so stop calling them.
This year was especially infuriating because they actually went way overboard with letting things go. 99 times out of 100 I prefer for them to put the whistles away vs calling all of the weak calls but this year was too much. Letting super obvious trips and super obvious play affecting penalties go for the sake of game management was clearly giving advantages to teams and some teams clearly abused that. This year was that 1% of time that I would actually have preferred they just consistently called the ticky-tack calls.
Let teams muck it up, let teams compete, let teams hit, but if it prevents the other team from playing hockey fairly then make the call.
