Dredd is tasked with showing an alien journalist around the Mega-city and told to be a bit more civil, what could possibly go wrong? The brevity of the story means there is no time to do anything interesting although the alien’s hyperbolic scribblings are quite amusing. You can guess how it ends.
Funny aliens, like talking animals, are a bit of a mixed bag. They tend to blunt the sci-fi edge that Dredd has when just played for laughs as they are here. Off planet or with a purpose, like the Kleggs, they can make a positive contribution but in this case, not so much.
