Why has no one come up with a reasonable explanation of how the platform/boards/ballisters/railings/bucket/sand/cueball/who-knows-what-else are so securely balanced on four linearly placed vertical posts without falling over? If there weren't apparent movement behind the castles (has it been determined whether the platform is behind the castles, or in front of them?), the balancing act would lend credence to the theory that this is flat world. On the other hand, if it was flat world, various things like Cueball, Megan, the boards and the ladder wouldn't be seen as different from the front and side views; they would only have one view. And a flat trebuchet wouldn't work. OK, so it's 3-D and the actors here have a sense of balance worthy of the best Ringlling Brothers act. But, notice the ladder; when the platform was first being built, Cueball placed the ladder edge-on to us. In that position, they were unable to reach it from atop the platform. It has been repositioned now flat to us and leaning on the same pole as before. In this position, the top of the ladder is actually further from the edge of the platform than it was before, yet the platform is now somehow accessible? I think we're left with the only conclusion - none of this is real. It's just a made up comic world with no reality. Oh sure, there are those of you who will profess that the Lord works in mysterious ways. That may be but even mysterious ways have some grounding in logic, physics and reality.
