An extra point for mentioning Abbott and Costello.

Rating: 9/10 (1 December 2016)

I did not want to see this film, but it was the only thing showing first thing in the morning when I had the opportunity to get to a cinema. I'd seen the trailer and it didn't look good. I was more than pleasantly surprised. There's real emotional power in this film, borne from a strong (cerebral) script, delivered by a director in real control of the material, and a standout performance at its center.
Everything that can be said, has been, so I'll keep it simple. If you're a parent, this will hit you right in the gut. It's not a film for 18 year old's hoping for Independence Day style explosions. This is a film for emotionally mature people and those with half a brain. That rules out all the naysayers (mostly active in the forums).
Judging by the scores however, most IMDb people do have an appreciation for something stimulating and engaging, elements lacking from most superhero/remake fodder today.
I love Abbott and Costello movies, so really appreciated those references and the Sheena Easton gag, lost on many I assume.
It's not a film about special effects, but I'm really glad I saw it at the cinema. It didn't allow me the opportunity to pause it and wander off and come back to it. I was drawn in emotionally and held captive, in a particular mindset, for the duration of the story. As a parent, there were tears, I'm not ashamed to admit.
I hope those younger naysayers embarrassing themselves in the forums get the opportunity to revisit this film in later years and feel its true worth. I for one, haven't felt this emotional in a film for some time.
