Thanks to Hacking Netlflix, I was able to get a sneak preview of Blockbuster Rentals. First, here's a screenshot of the homepage in case they take down or move the beta (click for full-size).

So it looks like they have 5,000 more titles (20k vs. 25k) and are two bucks cheaper. The site doesn't look as robust or user-friendly, but I'll reserve judgement until they're out of beta. The biggest issue for me is ease of use. I want to be able to have the two-day turnaround I have right now and I want to have a robust recommendations system. Netflix's is adequete, but not perfect, so there's room for improvement here.

I'm signing up for a free trial, so I'll report back in a few weeks.
