As much as I loathe saying it, England did play well the last few games, while Australia seemed to be strangely lacking (unlike earlier in the series where they could do no wrong).
I must admit the stupid rain was my main issue with the last game though. While I sort of get how the whole D/L system works, I can't justify mentally the fact that at one stage the game was reduced by 17 overs, yet the target to get only dropped 34 runs or so. While the reduced time does make it somewhat easier for the second team (so a reduction at the ~5 runs/over rate is maybe a bit excessive) how can they reduce it by only ~2 runs/over???
