Thiem losing early didn't help the tournament at all. But there've been quite a few interesting stories to watch this year:
Can Roger win any matches at Slam-level?
Can Nadal break the Slam record?
Will Djokovic put the 2020 final behind him and show up for the upcoming semifinal?
Just how far can Medvedev make it at RG?
What kind of statement will Tsitsipas make in this tournament?
The problem is that those stories don't often come with good matches. In fact, I can't think of any particularly outstanding match. Even 2019 had the really good Tsitsipas-Wawrinka 4R and 2020 had a decent Tsitsipas-Djokovic semifinal. Unless the second semifinal and the final deliver, I won't be able to list any particularly impressive matches.
