The unGodly amount of material in Hollywood is the only reason readers unfortunately exist. A better use of your money might be to purchase 3 or 4 of your favorite screenplays and read them. Look how they are written and use that format. Buy a couple text books on writing for general guidelines. Then take your money and start hitting the streets meeting people. You're best bet is to have an "in" at the place youre pitching your material.Is it a bad book? No. Is it a must have? Absolutely not. A few good pointers, but alot of self-centered, self-important tips that won't make or break your deal. If you have an original idea or a new twist, that may be enough. The best bet is to take that original idea (if there are any left)and punch out a good screenplay. Do your homework, get good honest feedback and don't give up.
