I was really looking forwards to this: Whereas "Asterix & Cesar" wasn't great, they seemed to have found their stride with "Asterix et Cleopater" only to inexplicably throw it all away with this heap of rubbish. Where shall I start: The cast.
Clovis Cornillac - catastrophic. There isn't a hint of the quick wittedness and light footedness you expect of Asterix. Instead of being the mainstay of the film, he's a sideshow: Unfunny, uncharismatic. Bring back Clavier!
Alain Delon? I nearly wept! He's an all time legend. Cool, hard, dangerous. And here? A creepy buffoon. His worst role. Ever.
That's enough. Now the plot: In Asterix & Cleopatre, the writers (and director) managed to update the Goscinny original comic spirit and clever references very successfully in my opinion. That is, without sacrificing the flow of the narrative, and without over-emphasizing modern references. That is, they didn't get in the way nor did they hobble the Goscinny narrative.
These clowns seem to have completely missed the plot. The unsubtle references stick out like a sore thumb, and the things referred to will all be forgotten in a few years.
But more fatally for the plot: they've glued together episodes from different Asterix books with elaborate pastiches to try and re-establish some sort of story logic.
Then, they have seriously warped the actual olympic games narrative flow. The plot they've come up with leaves you constantly thinking "What? How ... why is this happening now? Where is such-and-such gone?" and most importantly "hmm, was that joke supposed to be ... funny?".
All in all, truly catastrophic. The only saving grace is - I supposed toddlers might find it exciting.
