Agree.
We were taken as kids on a re-run at the Odeon and left early, bored.
Came across 2001 years later and loved it - unique, compelling, clever and that soundtrack!
Reversal of Fortune, a boring 1990 film with Jeremy Irons about Claus von Bulow. So boring, I fell fast asleep watching it at the Brighton Odeon.
Hard to say about films you've only watched on TV, as you can change channels early on.
