Mine was excellent .............. up until she and her hubbie went to the airlines!!! Don't blame her for that one iota, but it only then became apparent how good she was.
Right from the start it was rammed home to fly safely and professionally, but without removing the fun element. Getting nagged at in my second lesson for busting my requested altitude by 50' was good for me and I missed it later on, when the following instructor often didnt comment on a 200' slip away from the desired altitude, though he was hot on direction.
So bit of both ... good and bad
