I found it funnier than I thought I would tbh. I did feel some of the humour was slightly forced (The scene where he farted in the restaraunt at the business men) but overall brilliant.
I also loved how unlike most comedy villains Giovanni Ribsis character was pretty menacing.
One of the standout sequences for me was him dancing to Tiffany 'I think we're alone now' while his son played Hide n Seek with Ted, great character. Surprisingly funny film.
