Free+Waid=In my collection. If it sucks then the free issue will be it for me.
With the way the all the comic companies decompress every story sometimes it takes more than 1 issue.I think that one issue is usually enough to know if something will be appealing to you. So if you have a set budget for comics in a given month, my recommendation would be to stop buying the title you enjoy the least and pick up something new each month until you find something worth sticking with.
There are some that do.I don't think that everything any company puts out is all great or all garbage. Each company has its fair share of strong books and its fair share of weak ones.
The reason that in this thread I think it's relevant to bring up other publishers and other genres is because the OP expressed dissatisfaction with the new Avengers lineup. And his alternatives to this seem to consist of reading DC instead, or wishing that the Avengers book was comprised of a different set of characters who are equally derivative.
If someone was saying that they were sick of what Image and Valiant had to offer, I'd probably bring up Marvel or DC to them.
