Say what you will about Maximum Carnage and The Other, these were successful comics for Marvel. They sold out and remain in print. Even if I didn't like it, Maximum Carnage still pops up on reader lists of the top Spider-Man comics. Clearly readers were comfortable buying stories that were unabashedly 12 or 14 parts. So, why don't we have more of these?
I'll note that there have been well-received longer stories that could be seen as consisting of smaller arcs, such as DeMatteis' Harry Osborn saga, or Mark Millar's run of Marvel Knights Spider-Man (initially packaged as three four issue arcs) but I'm curious about why Marvel doesn't just sell something as a 15 part epic.
Is it that the last decade of Spider-Man comics haven't been crossover friendly due to the creative teams? Or is there a different type of storytelling with event books that have peripheral mini-series (See Spider Island, Spider-Verse and Clone Conspiracy)?
This isn't something I necessarily want to see, but it seemed successful enough that I'm curious why it hasn't happened more.
