I really like the show and hope it returns next season with The Walking Dead. It seems to be the right show to have inbetween the two airings of the Walking Dead.
Looking at thr stats, it might make sense to bring it back as well:
Last fall the seaon finale of Hell On Wheels brought in 3.8 million viewers. The average for that show was around 2-3 million viewers.
The average for Comic Book Men is 1.5 million.
Now I know you might be saying how is that good for the show. It has nearly half the audience than Hell On Wheels. But think of this, with Hell On Wheels...you have to pay for:
1) a cast that includes such actors like Colm Meaney that get paid way more than a Ming from Comic Book Men
2) a cast that is a lot more than the 5 cast members on the Comic Book Men
3) an eleborate set that costs to make, repair and update...let's face it...the Comic Book Men store is already built and costs little to maintain since it's an existing business
AMC is all about getting all the bang for their buck that they can. HoW has already been approved for their 2nd season, but maybe AMC might try to put them somewhere else than right after The Walking Dead. If HoW is so strong (2nd highest watched AMC show), it might be utilized better by putting it around some shows that needs some help in the ratings.
Comic Book Men is cheap to make and fits right in with a show that was created from a comic book.
