Nah, each & every character fit their role perfectly! From Sindri to Tyr to Mimir, the Thor household drama all of it. Also, Atreus is believable, Kratos is an acewhole! He has always been like that BUT now you see him transform, their chemistry is amazing.
Storywise Helheim spoiler ahead..
That Atreus hug scene man, seeing Kratos absolutely melting & later apologizing to him! Man, that was totally EPIC!
I also love Kratos open up about his past with the other characters, all the nods & mentions of the previous games from GOW 1 & chains of olympus etc. it feels so awesome just to slow down & pay attention to their chatter.
As for the combat, I like the juggle system, the status effects which you can put on the enemies (Frost to Burn & vice versa.) are nice & highly recommended but the weapon switchin' needs improvement to make the most of it!
