To the Offbeat films...

What exactly is the defintion of parallel and offbeat cinema ? I was wondering about this today and I thought, "is it cinema which (supposedly) do not have Bollywood masala elements, formulas, stories etc." Many esteemed industry persons have said that parallel cinema is a art. I personally have very little interest in this so called parallel films or multiplex films. Why ? I go to a hall to be entertained, to escape from life. Yes, of course, I do want to see larger-than-life cinema, I do want good triumphing over evil. I want to be entertained, I want to forget my problems for a few hours. If I want to watch reality, I might as well stand outside.
