@kincaid The Max is probably now quite a decent aircraft. It has the compromised version of the LEAP because the landing gear is too short, but it does surprisingly well regardless.
But as originally produced, it was a murder plane and unfit for purpose, simply because of this stupid bit of software that made piss all difference to normal flying, but could be tricked into killing everyone on board remarkably easily.
It's still there, but it's been defanged now.
