Query: Unsatisfying

I love independent films and art house fare but this one is a major disappointment. Others have criticized Drive as being too slow, but it was spot on and very satisfying. It is also a good comparison in that it similarly has an abrupt, somewhat incomplete end. But Martha Marcy May Marlene seems so slow because there is no character development at all. If it wasn't for all the flashbacks the viewer would feel as if they were watching someone take a nap. None of the main characters has any arc or is changed by the circumstances. On top of that, the movie comes to an abrupt end just as you are expecting some kind of interesting plot development, ok any plot development. I'm fine with movies that leave you thinking, but this one leaves you thinking, "Where's the movie?" I agree with another reviewer that there is a film waiting to be made about leaving cults, but this isn't it. The actors are good, but not great given they have very little to work with.
