“The Batman minifigure isn't as interesting because it's the same one is in a couple of sets plus he's also in a plethora of other ones. The Phantom Zone is very cool especially since it doesn't appear in any sets but it does connect to the Arkham Asylum (70912) where it has... More the Phantom Zone Projector. If you're not into the polybag, it does make a good parts pack.”

“More interesting is the Kryptonian Robot Guard. A lot of small and spiky pieces are used to give it a menacing appearance. The guards surround the Phantom Zone Projector in the film, impeding someone's mission to retrieve it, but they are not encountered by Batman so... More including him in the set is a bit of a shame particularly as the character that does come across them is equally important and comparatively rarer. It's rare for flying things in polybags to be provided with a stand so the transparent one included here is most welcome.”

“For a 59-piece set, there's a really solid selection of dark red elements, including eight 1×1 tile clips and four 1×3 plates, as well as two dark red headlight bricks, which have been quite rare in recent years, unless you count expensive sets like Assembly Square or the... More Death Star.”
