2.0 is actually a FLOP but then there are stupid ass people in trade who for RTs and be in good books of fans/producer inflate numbers.
If you are interested, for South India box office use http://cinetrak.in and for Bollywood use BOI but with grain of salt for some films. Like Kalank they are fudging it by 15-20%.
On serious note, I am more impressed with this 56% than opening day of 100%. There will be more shows added for Friday and Saturday so people will be waiting for them.
By tomorrow/tonight Aries will be sold out for weekend.
Edit: The theatre basically jump started pre-sale as officially pre-sale start from Saturday Midnight and now they have stopped the sale online.
