I can see the 757 being a handful for an inexperienced pilot, but it is not a difficult plane to fly, or to land.
I needed an extra sector in the 757 as well, but we trained in the 767-200 and 767-300 every other sector, they each fly a bit different.
(probably had 35-40 hours total line training, the last flight from Boston a day or two before 9/11, same type and same airline that got hijacked and flew into the World Trade Center.
)
Anybody needing a ridiculous amount of line training to land a 757 should find a different profession, it is not an SR-71 or some other exotic machine, lots or rudder and aileron/elevator control.
