charlie: I'm curious as to why you want Belgium to get crushed by Brazil. Because they beat Japan? Fairly? With dignity and respect given to Japan throughout? Genuinely baffled as to what you have against Belgium who were happy to offer hugs and arms over the shoulders of the Japanese players after the match and didn't cheat once, while Brazil - and particularly Neymar - have been diving left right and center.
As for the issues of theatrics, how do you solve it fairly? My opinion is that if someone shows excessive signs of pain such as Neymar did, they should be ordered off for treatment. The foul can still be given, perhaps even a red card, but if you're in that much pain you shouldn't be on the pitch, you clearly need medical attention - off the pitch - while the the rest of the players carry on without you until you are deemed okay. That should be at least two minutes off the pitch for you if you are rolling around like that and screaming in agony. If you can get fixed up faster than that then perhaps you should just stand up and shut up.
