My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.

Ex Output:
Bad review

There was never a doubt for me that this would be a bad movie. I thought there were few original ideas but the execution of those ideas are terrible. The acting is bad, plot and dialogue poor, sound effects horrific, special FX's awful. One can only imagine the movie cost what it did to make, because even if you got rid of most everything wrong, some bits you'd leave in place, you've lost 90% of your budget.

Ex Output:

Bad review
