Re: Will this be worth a watch
I barely remember Dead Ringers so it may be my issue. But I've been pretty hit-or-miss on Cronenberg generally - I liked eXistenZ, was indifferent to Videodrome, didn't like Cosmopolis, but weirdly enjoyed Maps To The Stars. I guess Jeremy Irons was good in DR, but I tend to not get that excited about an actor playing multiple roles, in part because any professional actor should be able to play multiple characters who are very different from each other, so it's not all that impressive to me if they're doing it on the same shoot. (E.g. I never got much out of Orphan Black, and Ewan McGregor on his season of Fargo didn't do a ton for me.)
I've seen The Fountain but I barely remember it, and honestly I have no idea whether I like Aronofsky - Pi wowed me in high school but was less impressive when I was an adult, while I went back and forth on whether Mother! was awesome or terrible.
