I don't know if it's just me being tired with Supernatural, because "The Mentalists," a typical monster of the week, left me wishing for more--not necessarily Leviathan more, but something the season can really grip on. It's nice that we get a funky ghost story, which had plenty of funny lines and the most solid plot in a long time, but the Sam and Dean conflict, running underneath this episode and season, was again not very inspiring.
Score: 8.6/10
