Too much Holt going out of character this season?
I love Holt. He's my favourite character in the show. But what I've always enjoyed most about him is that even though he's such a serious character, once in a while he does something surprisingly over-the-top or makes a joke (the best moment in the show so far is him showing Jake pictures of him at hula-hooping class, deleting the pics then telling Jake "No-one will ever believe you!").
That being said, I feel like they're giving him too many of these moments and it's too much. It used to be a few a season, now it seems like there's a few per episode.
