twenty20 is more intersting than ordinary cricket,because its all about power hitting and restricting your opponents to a minimum total.But you can not see any classic cricket shots being played in the twenty20 version.Its more like baseball hitting.so together with the entertainment twent20 should be carfully balanced with the ordinary way.
20-20 world cup was fantastic, But the IPL was SHI*
However when you have two world class sides that are fairly evenly matched, Nothing is better than test cricket then, Plus the Pitch is also really important in test cricket. I hate flat tracks.
Ive noticed that the younger generation are more fond of 20/20 than the olders. But I still think theres a future for ever format of the game weather its Tests, ODI's, Pro40 or 20/20!
