I give the plot an A+, I give Robin William's Creepy performance an A++, but somehow in total it only equals a mid level B. I guess maybe the story didn't live up to the plot and performance, and/or maybe the execution wasn't quite there? It just seemed like the first 40 minutes were a near flawless set-up for what you just know is going to be an epic and unforgettable story! but it just doesn't seem to materialize? Or maybe my Expectations were the problem and I'm being an overly judgemental Prick? Bottom line, Robin Williams Creepy performance makes it a must see movie, in my Prickish opinion.
