There's more to say here about downloading and PSP syncing, but I'll pause to spare your eyeballs and say more later. Overall, I'd probably rate it somewhere in the B / B-minus range, leaning toward a B-plus for effort. With threadbare video info, sluggish load times, sequentially incomplete shows, no HD version purchase option, etc., it feels a little rough around the edges. Expect to see dozens of tweaks in the weeks and months to come as users weigh in on what's hot versus what's not.
In other words, like anything else these days, file it under "Work In Progress."
