Unfortunately for the actors in this film, it seems the writing isn't enough to be gripping in a weird way. One would also imagine this is a film that came about after industry folks knew about Bruce Willis' aphasia (and by this time were feeding him words to repeat through an earpiece). The ethics of that don't feel hazy, they feel wrong. You can tell by the completely monotone delivery of short bursts of language, mostly while looking in a certain direction, like one does when listening, or remembering, but not usually when experiencing dynamic emotions through the scripted words. Or at least acting like it. Bruce Willis is great and I won't judge him based on him being wrung out for money after experiencing an illness specifically disabling to his career craft.
I hope I get a chance to see the other actors elsewhere to experience what art and entertainment they can provide.
