It sold 1.5 million copies based on it being a movie tie in to one of the biggest movies of the year. It was a valuable lesson going forward, very few movie tie ins are worth buying still
reviews didn't come out until after release, it was pre internet, no one could know how bad it was until it was too late.
reviewers hated it, I can guess not many of the 1.5 million buyers were real happy either
I don't know how much of an effect it had on the crash. It is mentioned but its just one of many bad games that didn't help.
