I think international football is more like that anyway, as the coaches don't get lots of time to create a unit that is as well drilled as club sides. Then in the WC in particular you have all the contrasting styles of teams and players, and the desire to win is so great the players go that extra mile and it creates a spectacle. There is little time to redeem yourself if you don't win games so the emphasis is on winning games.
I agree that at times it is very amateurish but it shouldn't be compared to club football anyway for the reasons above (never mind the tired Allegri shit). I've found it refreshing at the same time, the WC often has this naive and exciting feel to it in comparison to something like the Champions League which is such a high level tactically and in terms of quality.
