Depends how you rate a WC. This one has had more upsets and underdogs have done well, so by that metric, it's a candidate. But the football has overall been very dodgy. Nobody is dominating, nobody is an obvious candidate for the title. Almost all the games are won by a single goal. Close matches are good to watch, but these aren't the things that get remembered. You remember the exceptional sides that were clearly the best in the world.
I don't think this WC will go down in history as anything other than an unusual one where all the expected favourites were below par, unless some massive underdog like Croatia ends up winning the whole thing. While there have been a lot of close games, are people really going to remember any of these the way we remember the 7-1 Germany-Brazil game? Or the absolute brawl that was the Netherlands-Spain final? What players have stood out? What team has excelled?
There's a penalty in every other game. While they've generally been correct calls, it's still far more penalties than is good for the game. There have been some close, tense games, but there haven't been any that really got me excited. No games where one team proved themselves to be a candidate for the title. It's been smaller teams slightly overperforming and bigger teams slightly underperforming, day after day.
Kinda feels like when Leicester won the PL. That was certainly a remarkable and unusual event, but at the end of the day, it was a season where just about everyone else was total shit. It wasn't good football, and other than the fact that Leicester won the title, I don't remember a thing from that season. I think this WC will be the same. You'll vaguely remember that a lot of slightly unexpected things happened, and then possibly that Belgium won it or something. But there'll be no individual games that go down in history, no players who put their names on the map.
I prefer WCs where some team took the world by storm and the best players proved it on the biggest stage. Not ones where a lot of wonky things happened and all the favourites were mediocre. That sort of thing is pretty forgettable to me.
