Imax is famous for its big screen is awesome for 3d movies. But there ends the good part. Problems start with parking. It is outside, one has to come out and walk on the road to take car after movie. The layout of seats is such that there is no central aisle. God forbid if you have to empty your bladder in the middle of a no break movie.
I ended up suffering at the end of the superman movie. You rush to the toilet and find them inadequate for the number of audience so wait in a queue. To top it all, there is the problem of probably black ticketing nexus. After online booking, they say movie is cancelled and sell the tickets in black.
