Challengers is possibly the worst movie I've seen this year. Why do people love it?

I'm surprised to see that the critical reception for this movie was so high. Just had the displeasure of watching it in a flight and it was insanely boring.

First of all: it's artificially long. It's only over 2 hours because of excessive slow mo and cuts. That part near the end where Patrick gets warned for stalling and then it takes like 2 minutes for him to serve was infuriating to watch. The soundtrack is all over the place, some random electronic beatsuthat are suddenly cut off.

The characters are all extremely unlikeable. Art is a major pushover with basically no will of its own, Patrick is a nihilistic womanizer, but Tashi takes the cake. She's probably the most selfish, shallow, self-absorbed and unnecessarily rude/hostile character I've seen in any film for the past years. Her entire purpose is to sow discord, she doesn't care about anyone but herself, she insists she's not a homewrecker but she spends the film symbolically and literally doing that

The plot goes absolutely nowhere, the whole fllm was just a vehicle to see which character you'd end up hating the most. What exactly is so beloved about this movie?
