Just watched it tonight (well 20 minutes of it) and it was awful.
After seeing David jason play a usually confident Del Boy it is sad to see him play an incompentent person who is always being told off and ridiculed.
I have to say he is also not very good (or too old) to play the slaptstick that much of the part requires.
He needs to find a part more approiate to his age. He may have been better as the "boss" with a younger actor (a Rowan Atkinson type) playing the bodyguard, like the "Johnny English" role in the Rowan Atkinson films. Aktinson is far better at this type of role.
The script is also pretty poor, makes you wonder how it ever got made.
