Completely agree. I thought that the actors did the best they could with what they were given - the directional style was very strict & left them with little freedom. I found the story very bland; as you said, the fact that they were all the same character & therefore had no interaction very disappointing; and I found it very distracting that they had to keep checking their scripts to check what they were to do next. Not for me either!

This sounds like going to the dentist!
