I subscribe to both Pilot and Flyer and enjoy both. If I had any real complaints, then I would no longer be a subscriber. I think that's the key point here. If you don't like what a magazine has to offer, or feel that it is misleading you in some way, then don't buy it.
Leaving aside stating the bleedin' obvious, I do have one minor gripe. There isn't enough opinion, or enough writers who are opinionated. I suspect that it amounts to the same thing. A bit of controversy; a smidgen of confrontation; a soupcon of provocation; something that stimulates lively debate - these things give a magazine more of a pulse. Imagine how dull PPRunE would be if every thread discussed what a lovely day it is and just how great aeroplanes are. More establishment-bashing would suit me just fine.
