I watched almost every game, they are all in the middle of my workday so I have something to watch in the background so it's perfect.
Shocking what happened to Eriksen and I'm appalled by how some broadcasters handled the situation as well as UEFA not canceling the match outright. Finland was good and they proved that against Russia (even though they lost the game could have gone either way), but Danes were simply not in that game anymore.
Otherwise, great tournament, quality of matches was higher than I've seen on Euros/World Cups in a while (at least considering group stage). Belgium and Italy started strong and there were no major upsets besides the Denmark - Finland game. There was no bad game except maybe Spain vs Sweden. My favorite so far was Netherlands vs Ukraine.
Since Serbia is not in the tournament I'll be rooting for Macedonia, but it will be a miracle if they advance through the group stage. Otherwise, my favorites are France but it will be very interesting in the knockout stage since I expect Belgium, Portugal and England to go through (as well as Italy who secured their place in the best 16).
