I think it's simply ludicrous to keep basing the success of a new movie on its opening weekend box office receipts.
The only way to really tell how successful a picture was, is to measure how many discreet tickets were SOLD. With ticket prices continuing to rise in urban areas to as much as $10 and $12 a ticket, this "blockbuster" trend will continue, when in fact, overall ticket SALES have fallen due to competition with cable, DVDs and the internet.
