I've refrained from commenting until now, but I think there's little doubt that the WC hasn't quite lived up to expectations so far. Without wishing to go over points others have made, I think this is due to two main reasons:
1) The crowds have been shocking. This is certainly due to the reasons listed previously in the thread & has removed any semblance of the elusive "Caribbean flavour". The heavy-handed security at the stadia seems like some gruesome ironic joke, given the failure of "security" to stop the murderer(s) of poor Bob Woolmer. Not seeing the wood for the trees is I think the expression.
2) The cricket has been fairly ordinary too; I think we've seen maybe four genuinely decent contests (Ire-Zim, Ire-Pak, SA-SL, and Eng-SL) & even in those it was the closeness of the score rather than the brilliance of the cricket that kept us enthralled. I don't think we can blame the format for this depressing state of affairs; despite the assertions that an associate can take out a big-8 side with one result, this simply isn't true. If India had beaten Sri Lanka or Pakistan had beaten the Windies the admirable wins for Ireland & Bangladesh would've counted for nought. I think the real reason is that, Oz aside, most of the competing teams are fairly ordinary. The Commonwealth Bank & Chappell/Hadlee thingies made some of us think that the chasing pack had closed the gap, where in reality they were probably exactly the foot up the arse Australia needed. Buchannan's wish for a decent contest may actually have not been the dumbest request ever.
Hoping for better from the remaining games.
