As to Eli Roth, i find his films entertaining up to a point. I don't think anything i've seen by him has been great or broke any new ground but they were enjoyable in their own way.
I haven't seen Knock Knock yet but i enjoyed the original film that he apparently ripped off/remade.
The Seducers/Death game with Sandra Locke.( Clint Eastwoods old bird).
