i watched ROTJ last night and realized that the scene where the tie fighter crashes in to the star destroyers' bridge, is out of scale. a tie fighter is smaller then the bridge, about the size of an A-wing.
plus, that little itty-bitty explosion in the corner needs work.
also, when a tie crashes into the bridge and blows up not leaving a dent, why wasn't there a dent? i guess if sheilds were up, but still that explosion in the corner proves the sheilds are down.
