The conclusion was that he's a bizarre keeper, but that he's been a net positive in the PL this season (where United's problems are clearly in attack, not defence). Which isn't wrong.
He's mad some awful mistakes in the Champions League, which is why a lot of people appear confused. But then, as I said, bizarrely, he was by some distance the best keeper in the Champions League last season.
I only started replying because someone suggested the stats were nonsense because he was being compared to the Luton keeper. Well, I showed that he's actually comparable only to Alisson in terms of saves in the PL, and last year in the CL he was more important to Milan than Courtois was to Real Madrid.
To me, having seen how long his blooper reel is, that's bizarre.
