Conceived as an off-the-wall comedy and transformed from the script by the genius of Jim Carrey's improvisation, this was one of the films that defined the 90's. Completely crazy & and in no way taking itself seriously, it remains to me one of the definitive comedies ever made.
Carrey plays the titular detective, searching for a stolen dolphin and uncovering a schlocky scheme to extort a ransom. And that's basically the plot.
Without Carrey, this film would be nothing. Ace's tics and traits are all Carrey's creation and being allowed to let loose is what makes this film great.
It is also divisive in many ways, whether because of the humour and just how surreal it can be, or being retrospectively criticised & condemned/compared to today's standards by some people.
To me, if you are genuinely offended, upset or take in any way seriously a film character whose signature move is to pretend to talk out of his backside, then nothing that is written here will change your mind otherwise.
For everyone else, this is a comedy to laugh your head off to and gets better with each viewing. Highly recommended
