Let's look at one of the Free Comic Book Day books: "Free Bodies" from Mortal Coils Comics.
It has four stories in it! Yay, I like feeling like I'm getting a lot of bang for my buck (even when it's free). Three out of the four stories, I liked; not a bad average!
"Godpoint". Two lady janitors who relocate randomly whenever they sleep and then make sardonic repartee wherever they show up. But why I can't imagine. Honestly, I understood not a word of this story. Except for the one sentence in Latin, which was perfectly clear.
"Pit Stop". A nice, Vertigo-esque tale. Two (I assume) running characters, off on their usual magic-chasing errands, encounter a love-sick stranger who learns painfully, "Thou Shalt Not Steal." Has the patented 'quick crushing intimacy' with characters that moves Vertigo stuff along so efficiently. Love the air-brush-y art by Chris Srnka.
"Fetch". A silent film of a story, using only pictographic ballons (a la "Impulse"), about a store owner with a pet lion. Cute!
"I Didn't KnowThis Place Had a Cellar". Also cute. A light superhero parody tale set in a bar (the Hero Happy Hour series). I liked it, even if it only had one joke.
Perhaps this is a sampler of what the company has to offer and previous familiarity with the characters and their situations would help? I can't quite tell.
Oh, and I really liked the lettering by SnoCone Studios, odd as that may sound.
