I do 'acquire' a lot of movies - for a number of reasons, like many the cost of seeing something at the cinema does affect whether I go, however, also like others I have a small child and also work full time, so finding the time is also an issue (like loki2j has said you don't have to buy their food - and I usually don't when I go!) but another factor is I don't always want to see something Mr H wishes to see and vice versa, 'acquiring' allows each of us to see something we would otherwise have to see alone. Plus, again like others have stated the cinema seats are usually uncomfortable, the actual cinema usually cold, and then there is the issue of toilet breaks! (yes I do usually 'go' before I sit down, but sometimes the bladder is weak).
So, in answer to the OP's rant, yes I suppose I am lazy, cheap and a criminal - however, most copies I do get are pretty damned good - and allow me to see movies I would have otherwise missed.
