I've only experienced one escort mission so far and I rather liked it. It was frustrating, arduous, painful and bloody annoying all the way through but I got a massive pay-off in the end.
See, I was taking this mechanic guy to some place so he could unlock those sewers for me, he died twice on the way there and I resented the fact that I couldn't stab him in the neck with a homemade knife covered in zombie jizz, I kept muttering how much I hated him. However, a few more missions down the line and I find him again, outside the church, on the ground and beaten almost to a bloody death, I was so happy I did a little kick dance on his corpse and then teabagged him for 20 minutes.
