Mr. Freeze turns Killer Croc and Bane into super-sized monsters, and they bash their way through downtown Gotham until the Caped Crusader and his team of heroes join the fight in their giant robot mechs.
Given that it purely exists as an advertisement to sell toys, it's not unacceptable, but ever since _The LEGO Movie_ did the same thing, and was also really really good, that just won't really cut it.
Final rating:★½: - Boring/disappointing. Avoid if possible.
