Slow-motion makes everything look more malicious and intentional because it looks like players had more time to think that they actually did. The fact that referees don't seem to account for that is one of many, many problems. The red card today was just ridiculous, nobody wants a sport where that's a red.
I don't think it's even debatable that VAR has made the game worse, and two seasons in, we're not seeing nearly enough improvements to convince me that's about to change. Really hope the football community get together again this summer and put an end to this nonsense.
