No storm wave would break a statue that had been around for most likely over two thousand years, or even two hundred years.

Plus last season the ship was coming in by daylight and no storm clouds in sight. Nor do we have any hint there was a quake producing a tsunami. In Ab Aeterno it's a storm, and at night.

Here is what I think happened. When they wrote the Finale of Season 2, they showed us the statue, but they didn't want to give away the Egyptian mythology. They wanted to keep us guessing about aliens by showing the four toed ruin.

Then, in Season 5's Finale, it becomes necessary or at least desirable to show Jacob living in the Statue, and to reveal the original form of the deity.

OK, so now they have small kine problem. Statue needs to get broken. Also, we had a cool mystery with the ship way inland, but now we have to show how that happened. Oh, I know, let's bring the ship in on a big wave and hope no one thinks about it too hard. I think you are kidding yourself if you think these writers hold back because of continuity or the logic of physics. They have so much going on with this show, that they are constantly moving people along with something else to think about, and they more or less get away with it.

The scene with Juliet getting dragged into the hole last season was similarly flawed. There was some immense electromagnetic force let loose, which caused a lot of metal to get pulled into the hole including what wrapped around her. But there was all kinds of other metal in the scene that didn't even move.

Meanwhile people are shooting guns and neither the guns or the bullets are even mildly affected by this magnetic force. Why not? Because the writers needed Juliet to get dragged into the pit and they needed the shoot out to happen, and they weren't going to let a little hobgoblin like consistency constrain them.

I still love the show, but I think the criticisms are valid as to how the characters respond to information (pointed out by Colin). The characters get dragged around by the plot points.
