As seen as we have started to debate how bad he is I thought we could actually have a vote on it!!
Here’s some sort of case for the defence.
Good Cage films:
Face/Off
The Rock
Lord of War
Matchstick Men
Adaptation
Con Air
Cage films that I like but nobody else seems to 
Gone in Sixty Seconds
8MM
Ghost Rider
Next
National Treasure wasn’t too bad either although I couldn’t bring myself to watch the sequal.
