No they don't have porn. They do however have over 18,000 movies, including alot of new ones. its a monthly fee of $21.95 for as many movies as you can watch in a month. You log on and line up as many movies as you want in your cart. They then send them like 2 or 3 at a time. They get to your house in like a day or two usually no more than that. You watch the movie and drop it back into their postage paid self addressed envelope, and drop it into your regular mailbox. Then they send you a few more. You can also log in and change the order in which they ship the movies. Thats all.
I've been using this for months now and I average around 15 movies a month. Another cool thing I find is you can get a lame ass movie and you don't feel like you just wasted $4.99.
