Yep SC

A is mega buggy, had to restart one mission where you abseil down a building in a couple of places. Also has an idiotic control system whereby if you are sneaking at minimum speed the safe dials don't work - not ideal on a mission where you need to sneak up to crack a safe.....
I'd add NFS:The Run, even if you get past the fact it has QTEs in a racing game (W.T.F?!?) it puts hints using XB360 buttons when I'm playing on a keyboard so had to use trial and error to work out what buttons to press.
Assassin's Creed Director's Cut is unbelievably bad in one aspect, it takes 11 (ELEVEN!!!) key presses to quit the game with all sorts of nonsense thrown in (loading sections, logging in to profile... how incredibly retarded do you have to be to design a UI that can't be quit unless you log in first?). The fact it never got patched either is quite frankly ridiculous.
To be honest, for all the talk about "shocking ports" there are only a couple of things that really annoy me:
-Unremovable framerate caps
-Multi-function keys e.g. sprint/cover, use/reload etc
-Non-dynamic key hints (worst of all hardcoded to pad buttons)
As mentioned above (in relation to Deus Ex:IW) often games may be influenced by consoles in terms of their design but that doesn't make them a bad port per se.
