L&C is being written by Dan Jurgens, the darling of the Triangle era for Superman comics (though I think Roger Stern deserves more credit and love than he gets) and a well known name. Certainly the lack of a Johns or Bendis level writer has resulted in lower sales than if someone like that were attached, but its not like Pak, Tomasi, or Yang are super well known, sales generating names. I'd wager that Jurgens' name still carries at least as much clout as them, and the book still isnt selling.
There are a ton of things behind the scenes we are not privy to. There are lots of reasons for a book to succeed or fail on every level from WB's management to retailers to us fans. But I think, given what we know, the only reason L&C is selling as poorly as it is, is because there just isnt enough interest in it. All the other reasons Ive heard for its sales (no marketing, no variant covers, Didio is an evil wizard) just sound like excuses made by people who dont want to accept that their opinion is not the majority.
For the record, Ive enjoyed the book too. But my personal opinion is not a reflection of the market at large.
Misslane, just so you know, I dont mean "everyone" by that statement.
Dont mind the hyperbole, like I said, Im lazy.
