It will pull in the younger fan and indeed families due to it's format and how it is run. Action, music and all done and dudted in a space of 4 hours weather permitting. A great day out for the younger generation on the ale or a family wanting to experience what the sport has to offer. Like i said, i can see it's positives. I do however fear for the fans of this form of cricket once the novelty wears off.
Just personally like the test match cricket and watching how a game over 5 days is played. It's a bit like chess i suppose and does require patience and a knowledge of the game. Twenty20 is more like 5 a side competition compaired to the Premier league. Fun whilst it lasts but forgotten very quickly. If it brings the younger generation into the cricket fold then i'm sure it will have served it's purpose.
