Look, this is Ryan Reynolds, Dwayne Johnson, and Gal Gadot playing brilliant spies all trying to one-up and out-twist each other whilst jetting all over the world and getting up to all manner of classic espionage-based hijinks. There are more double-crosses than a game of tic-tac-toe, and a set action piece once every ten minutes or so, all of which is played with an utterly absurd amount of charm and cool by the main cast. Does it need to be anything more than that?
I mean, does the big reveal double-cross, "they were lovers all along" really make much sense? It's not awful, though a lot of the plot could logically be skipped if they just followed Reynolds' character to the jungle after he stole the first two eggs. There isn't much need for the whole FBI/jailbreak/mistress angles if they were just working together, but in the moment it seems fine enough. And yes, it's just plain stupid that a car from WW2 would just run like that, or that an agency intent on the preservation of priceless cultural artefacts would so brazenly shoot up a room full of lost treasure, most of which were likely far more valuable than the single jewel-encrusted egg they are after.
But these moments are forgivable because Red Notice is just a whole lot of fun; the actors involved are all obviously having a blast; and it keeps you entertained solidly throughout. It's not going to win any awards, but I'm more than up for a sequel.
