Now going slightly deeper, in cricket, there are two ways in which a wicket falls. It is either earned by the bowler or is given away by the batsman. My contention is that in T20 the latter is what happens about 90% (or more) of the time. Take a look at Irfan Pathan's wicket tally in this tournament. It is ridiculously high given the way he bowled.
It follows logically that credit must go to the batsman in this form of the game. The bowlers play a holding game. Either they stop the batsman from rampaging or they are muscled out. That is the way the powers-that-be want them to feature as well.
Now to go back to your original post - I would not claim that T20 is all about batsmen and not about bowlers at all. It is just skewed towards the batsmen. Next - yes, I do believe Mumbai was the overall better team. They lost their nerve where Chennai held theirs. That was the difference. One of my complaints with this format is that not necessarily do we see the best team win always.
Even in test cricket we have batsman commiting silly unforced errors and it is not always a great delivery that gets a wicket.
Hope you saw Murali Vijay falling to a catch taken near the ropes of Fernando. To an untrained eye it will look like a six which was just short or maybe he throwed his wicket away. But if you carefully notice, that particular ball was bowled at exatly the same line vijay loves to pick up the ball for sending over long on, but the twist was it was just slower at 123kp instead of his usual 135kph.
That did the trick, Vijay's swing was a trifle earlier and he ended up hitting the ball with his upper bat. Now if it had been a real slow one (i.e at around 110kph) the batsman would have read it and refrained from trying for a six.
That trait of adapting oneself to the format has made bowlers like malinga, ojha, tanveer and gul sucessfull whereas bowlers like ishant have failed.
Remember that not all batsmen have adapted to t20. Even a great like Sehwag hasn't adapted to the pressure cooker situation of t20.
I agree that the "bosses" want cricket to be dominated by batsman, but everytime this is tried the bowlers too come up with new innovations and keep pace with the changing trends (eg:slow bouncer, yorker outside offstump, etc)
And yes true, in this format the better team doesn't always win. This unpredictable nature of the game till the 19th over is what makes t20 so exciting. If the best team or player always won it will be boring like a steffi dominating in the 90s or a schumacher in F1.
Yes ads inbetween balls is irritating but will soon be stopped as a lot of media planners have critizised it. And why do we have to go after the 4 poor souls dancing in one end of a huge stadium. Why don't we consider them as just another add-on like the funny duck that walks when a batsman got duck out in the channel7 days. defnitley they are less suggestive than our filmi bollywood dancers.
