Wow, I'm surprised at the positive reaction so far, though I presume as far as this forum goes, dissenters are maybe holding their tongues - or there's just a lot of people here that didn't see the ODI Super Series.
I have been in favor of increased usage of technology for quite some time - I wasn't completely sure how the LBW stuff would go over on a time level - from what I've seen so far, it's been pretty good, although I'd like to see it in a little more action before I make a call on that. So far, so good, though.
I was reading an article at cricinfo by Peter English the other day, where he was criticising the adoption of these tech tools as being "too clinical and taking the romance out of the game.". While he has a right to his opinion, I feel that:
a) we've been watching this stuff on the coverage for years now, and I don't think it's taken romance, drama or grandness out of the game (and certainly, in the case of actual in-game use such as runouts, I think in some ways it's added to it) - it's just made seeing clear mistakes so frustrating. There's more than enough romance in a cricket game where the players of the game are concerned (particularly Hayden and Langer).
b) obviously the atmosphere during the Super Series wasn't that great, given people's reactions to the roof and the small crowds, and I'd be cautious about carrying that feeling into a judgement of these new abilities for umpires.
Nevertheless, traditionalists who feel that way are entitled to their point of view - my main point of argument has always been with those that choose to fight this concept on the basis of accuracy, 'cause it's an irrational and ridiculous debate to be having. One of the interesting things in English's article was his own admission that, in terms of getting better decisions - it worked. Not a surprise to me, but good to see that's the impression everybody's gotten, even some who were a little unenthusiastic about the merits of using the replays etc, some of whom have expressed a far more favourable opinion towards it since seeing it in practice.
