I actually didn't mind "Betrothed". I know that episode is hated by many, but I thought that the soundtrack in that episode (particulalrly during the wedding ceremony) was great.
"Stranded" was an OK episode, not one of the best, but a pretty good one if you're a Rob/Star shipper.
My picks would be "Bunny Raven", "Crash" and "Hide & Seek".
