"he is the best professor, I am so glad he is my supervisor"
to
"he is the worst supervisor, I am wondering how I can get the university to transfer me"
to
"he is the best professor, he helped me get a job after I graduated"
Which I think is a fairly normal rollercoaster ride.
I never got my PhD, my first day as a lowly research assistant in a university in central london (which shall remain nameless) I was given a professorial suite to camp in, and I remained there for 3 months, imposing furniture and a giant oak table and all. Another staffer used to sleep on the floor and park his bicycle there. Eventually I was evicted and sent to the top floor, an ex-statistics research unit teaching room, like army Barracks, where I and a fellow research assistant opened a cupboard to find the 10 Brunsviga calculators left over from a mechanical actuarial risk calculation exercise the department did for money up until the advent of electronic computers. Their entire previous 5 years work was completed in under 1 days run of the machine code on the new University of London computer in the early 60s. Oh, the Joys.
