This is such a great idea! Had a read through (most) of the previews and they all look very interesting!
As a 'new reader', I'd consider buying:
Hawkworld #5
Batman #15
Hellblazer #11 (never been interested in reading the comics IRL before, but this story arc sounds great!!)
Curse of the Phantasm #4 - the best creative team ever. Ever!
Also, Cyborg #6 - and picking up the previous back issues to get caught up.
And I had to vote for Cursed Dawn. It looked like there were some really great comics there and some wicked concepts. Great writers (Melville! Brubaker! Whedon! Waid!) and some really talented artists (Mignola! JH Williams! Sorrentino! Charest!).
I'm just getting into this, but I will start following very closely. The New Dawn line looks a little more accessible than the Age of Heroes one haha. Also, as someone new to these previews, I appreciate the "Part One of..." parts of the solicits.
