i never really loved the manual flying on FBW, but then again I never HAD to, it was always done for skill retention only.
I never liked direct law in the simulator on the A320, in this case cables, pulleys and a yoke felt better as they gave the sort of feedback you needed to manually control an aircraft without the computers.
Any new type is going to have teething problems, the airlines always finish off the testing program for the manufactures by which stage anything major should have been picked up. It would be uneconomic and probably impossible to have a new aircraft absolutely perfect before the first delivery, some faults will only manifest themselves under very specific conditions or after a certain length of time in service.
