WHY WAS THIS FILM SO BADLY BASHED?
Believe me, if they made a sequel and then a prequel, it did NOT flop.
The first movie made about $275,650,703 (at the cost of about $84 million) and the second $181,185,387 (at the cost of about $67 million). So they both performed excellent and were among the most high grossing films worldwide of 2002 and 2004.
People and critics just bashed these films to pieces for some reasons unknown to me, so they come up on new things to critic upon.
Somehow everyone got lost and didn't understand that these films were supposed to be live-action versions of the Scooby Doo cartoon. If you've seen the cartoon for 40 years you'll realize these movies are exactly like the cartoons, which is fun, colorful and silly. So I don't know why would people and critics expect Scooby Doo to be Citizen Kane or The Shawshank Redemption...
