"Can't bear to watch it anymore - as on Tv it looks appalling. Was really looking forward to seeing something well presented. I am sure the Ratings will show," Modi, who is in London, wrote on the micro-blogging site Twitter.
Modi said having the opening ceremony in a proper stadium would have been better rather than having it at the YMCA Ground.
"I would have preferred Opening Ceremony to be in A Stadium atmosphere, before a game. Rather than like a Concert like opening. The truth is I am in complete Shock - that a show like this can be staged. What was the Bcci thinking when they decided on this format," he tweeted.
Modi was the architect of the IPL and was in charge of it in 2008, 2009 and 2010 before being suspended by the BCCI on charges of financial irregularities.
