Rian Johnson has tiny hands. Another dull, absurd American murder mystery. I had a quick glance at the critic review section and was not surprised to see that of the eight that were immediately available the first six that awarded absurdly high scores were all American publications (one highlighting unexpected cameos- wow), the subsequent two with more modest scores were British. Europeans are spoilt in this genre and can discern between good quality suspense building mysteries and this.
Edward Norton's character (an Elon Musk caricature) is supposedly a moron yet he runs a huge multinational organisation where presumably someone other than Lionel may have spotted his inadequacies. He also (pre-alpha) helped all the other players achieve their dreams, not so stupid surely. Yet he was stupid enough to commit the murder himself, drive his unique car to the crime scene, invite the only witness to his island along with other friends, send an invite to the person he just killed even though he would be justified with no questions asked if he didn't. He also did not send the worlds greatest detective away immediately upon his arrival. The point being he's either a fairly intelligent, generous man or a complete moron with no redeeming qualities, depending on what the plot requires.
The other caricatures are shouty former model lady, attractive younger woman, lady politician, somehow a scientist (researcher), dimwit muscle man redneck, downtrodden ethnic help and finally twinnanigans and Truman capote.
Also when your character relies on luck (notepad in pocket) to survive it's just poor writing. It's also rubbish to have a twin show up half way through.
In fact the more I think about it this film is just really, really bad. Roan Johnson is just not a particularly good writer in my honest opinion.
It looks nice and it's mildly amusing so four stars.
