Well it took a full two weeks after release date (and a call to Walmart.com CS), but thankfully, my Superman Steelbook finally arrived.
I wasn't sure from the tiny picture what it would look like, but it's pretty cool -- with the translucent slipcover on, it's just the Fortress of Solitude. With the slip removed, the door opens for Superman and Krypto. I like it. The back is nothing special, just some crystals rising.

The movie was not that great so glad I saved some money and the steelbook sold out.

As soon as the Steelbook shows back up on Amazon, I attempt to add to cart and it either adds and won't let me check out or fails to add to cart. Might have to wait until the regular drops to Black Friday prices and give up on the Steelbook. Not paying scalper prices for it.

There must have been a problem manufacturing the standard 4k since it is impossible to find a slipcase in pristine condition with no dents or edge wear or white showlng along the corners.

I got 3 and none of them were close to perfect.

Wait, you didn't really like the movie, yet you bought 3 copies?

I liked the movie but not sure if I want one copy let alone 3.
