Well a couple of points:
Simeone, although defensive, doesn't really play Dyche-ball as there is more variation in their patterns of play. Additionally, Athletico benefit from being an outlier in a league that still puts a lot of emphasis on possession - almost every team plays the same way.
Also the game has moved on - it's why managers like Mourinho and Benitez (never mind Dyche, Pulis et al.) have found it harder to win. If a manager is only as good as the players they have at their disposal, why have Leeds come up with a team of mostly Championship players who have been transformed and are great to watch? Why did Man Utd win the league in 2013 under Alex Ferguson and then the same team (even with a couple of editions) finish 7th under Moyes the following season? There are plenty of other examples.
A manager should be instilling a 'philosophy' and style of play that runs through the club at all levels, which then improves the path to the first team and makes scouting easier as you are always looking for certain types of player. That is not parking the bus and signing grocks who'll leave a boot in every now and then. We've tried throwing money at it - let's go at it with a proper plan for progression.
Also, call me old-fashioned, I view football as entertainment. At some point I expect the team I support to actually try and entertain me. If a movie director you liked made a series of really awful, boring films over a decade plus, would you continue to watch them? I know football is different. But still . . .
