Pressure plates on the sidewalk which randomly reveal memories, in lieu of dialogue and actions which bring it up. "Intelligent" characters doing the dumbest thing people with any inkling of common sense knows is not good, just so the plot can advance. There was no story here, just set pieces and "payoffs" to things that never came up, and thus it has no impact. The special effects for the most part were excellent. That's why I give it a 2. Otherwise it would be a zero, this type of garbage is insulting.
