After looking at your website for a few more minutes I have a bit of advice for you.
Unless the YouTube trailers that you are linking to are monetized, BY YOU, I suggest that you set it up so a click on a movie on one of the Genre pages behaves the same way as on your homepage.
In other words:
When you are viewing the homepage, each of the images of the movies links you to another page, on your website, with: more information on the movie, an embedded trailer, an ad and an affiliate link. If they want to skip that page and go straight to the trailer, you have a text link below the image that allows them to do so. Good stuff here.
When you click on a Genre, such as “Action”, and then click on one of the movies, it pops up with the trailer and the user is never taken to the page that has the movie info, the ad and the affiliate link.
Perhaps you have a good reason for this but I figured you might be better off keeping the behavior the same as your homepage, for two reasons:
1: It’s a little strange to have such different a behavior, between the Genre pages and the Homepage, when clicking on a movie.
2: The page with the ad and affiliate link are clearly there to make you money… If you don’t let users get to that page, you’re likely to make less money.
Hope I was of some help.
If I wasn’t clear enough and you don’t know what I mean, let me know.
Also, if you need any more opinions on anything, let me know. =)
