AF447 and this flight show a lot of problems with some airlines needing more aggresive and competent junior pilots to not let the pilot flying put the flight into jeopardy through poor decision making and aircraft management.
It wasn't a problem during my career because our airline hired captains with experience and confidence in handling situations as FO's. We didn't let things get out of our comfort zone like we see some new pilots doing today with low experience. Unfortunately you get what you pay for.
