This issue had the random fun craziness of classic DC. The contrast between Night Girl and Dumb Bunny is especially great. Night Girl always seems too cool for these guys, like that one cute girl who hangs out with the nerds because her hairdo is not what the popular girls are wearing. The boy Subs are almost certainly all angry she goes out with Cosmic Boy, one of the jocks.
My favourite things about this cover is Merryman's "badass" face. It's such a great mockery of the ubiquitous "badass pose" covers which fortunately are passing into history, but wow that was a long 11 or so years. This is a great time for the I-5 to return, they are much needed to mock the adolescent-level comics that take themselves seriously and consider themselves "art" and great writing and so forth.
