Pretty poor
Mistimed humour - acting that lacks conviction - and a dreadful irritating performance from Pesci. I know now why I only originally saw the first 3 as I didn't want my fond memories affected.
It lurches between gory action and physically impossible car chases - no wonder the actors looked confused - the soundtrack was mediocre too.
But now for the first time in nearly 30 years I can only say I've seen all of them - and I wish I hadn't. Smiles and thumbs up for the first three - may this final installment rot in hell.
