It's a shame really, as EW, DT and the actor playing Grandad (Jack Shepherd) are all excellent but, the script was shite and I guess even good acting can't overcome that. My ds has Aspergers and I thought DT's reaction (struggling and realising his son's future was never going to be like that of the boys kicking a football around, in the park) was plausible. The only thing that moved him to tears was his son.
The final scene was laboured but DT's look was one of utter, sickening realisation that his wife was sitting where he had expected to be and his life henceforth was going to be secondary, to her. Many men have that look about them, in the face of a woman who surpasses them. I liked that.
It was corny and predictable though and it could have been excellent. The only "real" person, for me, was Jack Shepherd's "grandad".
