Henry is really a bad father
I'm kind of binge-watching this show and every flashback scene Henry is criticizing or putting Shawn down. He is also always ripping on Shawn's occupation. I get he's disappointed Shawn didn't become a cop, but his utter lack of faith and support of his son is noticeable on multiple viewings.
Don't get me wrong - love the character and the dichotomy between father and son. It's just something that has stuck with me.
