A bit of advice I got ages back: Never compare your project to another project. The minute you say "Well my book(show) is like <other popular book/show>", you've already biased them to think you're ripping off someone else.
Coming back to this comment, wasn't Star Trek initially compared by Gene Roddenberry to Horatio Hornblower ?
Not to mention "Wagon Train to the Stars."
This thread is still around?
