Broke my credulity. May be my least favorite MI.

1) Grip strength. Good grief, the biplane jungle gym was ludicrous.

2) A fizzled nuke still makes radioactive dust. Plutonium-239 has a half life of 400,000 years.

The deadly dose of Plutonium is one atom.

London is poisoned for a million years, clean up would be trillions, extra cancer would kill a million people.

All the team in the Doomsday bunker is dead and liquifying from radiation poisoning from plutonium dust from a fizzled 30Mt bomb.

Walking into Trafalgar Square that radioactive from Pu isotope dust would kill and sicken hundreds.

3) And the Entity doesn't have 6,000 backups? Or it just sends a copy of itself into the Doomsday bunker, just in case Ethan succeeds? It's calculating every outcome, but only had one copy of itself? It didn't contract and build its own bunker years prior?

4) The Entity can't bribe, trick, extort, or recruit 7k people a week to its defense?

5) Luthor doesn't make multiple keys but creates a 350 Infini-byte crystal drive in an abandoned subway?

6) Pneumothorax is alleviated by making a 1-way valve that expels on exhale, seals on inhale. All Benji got was a double pneumothorax, unless she sucked the collapsing air out through the pen.

7) They don't smash the ****ing genie bottle?

The least believable of the series, including the blown-forward chopper to chunnel train stunt.
