IMHO it was a poor show by the skipper to say yes to the base turn without the f/os involvement, and then not to help him when he was struggling.
There also seems to be an increasing amount of Captains who use the f/o as a kind of human autopilot. Typical complaints are refusal to configure the aircraft when the f/o asks, then to force changes when they are not required. This tends to show a lack of confidence on the capts part. Its amazing that when you leave an f/o to his/her own devices without breathing down their neck, what a good job they can do!
