Must disagree strongly with the other reviewers. It may have been groundbreaking and funny in the 70s, but not so now.
Reviewer Score: 2
The yardstick I use is their hilarious outing of two years later, Private Eyes. GGP is far inferior to PE. Put simply, it is that lamest of beasts, a comedy without laughs. Despite the charming presence of Sam Hui and the all-out mouth-open-wide antics of brother Michael and a cast of dozens, all of the gags just fell flat for me.
Deal me out of this one !
