I have had very good luck with the Hulu WatchList except it is not my userid/profile like Netflix. However, I have recently switched to using WatchAid which brings in content from all of my Apps (Hulu, Netflix, CBS, HBO etc) so that I now have a personal Watch List since it is based on iCloud ID. We have multiple TV's in the house so some have a different iCloud ID Logged in. Just wish there was a FAST SWITCH Option to have multiple iCloud ID Logged into the same TV.
I was hoping the New TV App from Apple would as good as WatchAid or better but so far in the beta I am not that impressed (only on the iOS so far). Somehow, I think the design is a problem in that it may rely heavily on the Apps themselves. WatchAid works independent of the Apps from Open Source Guides (I think).
