And the loss of the Executor simply is not the example of flaws being found and exploited. It's an example of unrealistic luck and outrageous stupidity joining together. That scene annoys me almost as much as the ewoks.
Why does everyone make such a big deal about Executor losing its bridge shields? Am I the only person who remembers that Ackbar ordered the Alliance fleet to concentrate its fire on the Executor? That means every Rebel warship and any Alliance fighters which didn't follow Lando into the Death Star II which could maneuver into position to fire on Executor were shooting at Executor. Under that kind of firepower even Executor's shields wouldn't have lasted long.
Your not the only one who remembers it. The loss of the shields is not the point of contention. The problem is that the Executor did not explode under the combined firepower of the Rebel fleet. It lost control after a comparatively miniscule, out of control, fighter rammed it in EXACTLY the right place to take out command center. Which, after we saw how big the tower front was when Luke and the gang flew past in that captured shuttle just seems a little improbable at the very least. Not to mention: why didn't a ship that big have at least one fully staffed auxilliary control room that immediately came online? These just seem like reasonable critiques to me.
