Couldn't agree more. I've just finished a trial with Love Film and I can't say I'm too impressed. Their priority system for discs is just messed up (they seemed to send me films I'd set as low priority on a regular basis), they'll only send you one disc from a boxset at a time (inc extras discs, which is just stupid) and their pricing scheme isn't as generous as it might first appear.
Also, Blockbuster had some pretty good ex-rental sales and I picked up plenty rooting around in there. Online rental sucks
