Positives:

My first game since Luton away in Feb 2020.
Team selection and formation (hardly rocket science).
Youngsters got a chance.
More effort than recent games (a basic requirement for a professional footballer).
Evans looked useful when he came on.
Chris Wilder was in the stand. (fingers crossed)

Negatives:

Terrible football (not as boring as under Harris but still absolutely rubbish).
Complete reliance on aimless long balls (not one player looks to get the ball down and pass it).
Very passive until late in the game with little pressure applied to the opposition (see midfield in the first half).
The contrast with the way that Fulham played (pass and move, ball on the floor, lots of movement, playing out from the back, almost never going long) was almost embarrassing.
