unprofessional/sucking

So I’ve been having a bit of a pet peeve with a lot of the reviews of the mini-comics lately.  A lot of folks are saying the artwork is “amateur” or “unprofessional.”  My problem is that the are is intentionally highly stylized, that’s how I pick who to work with.  Sure, it doesn’t look like Dave Sim or Alex Ross or X-Men or Spider-Man.  Saying XO is amateur is like saying Peanuts is amateur or Farside is amateur.  To say you don’t like the art is fine; honestly, I’m a bit surprised when someone likes the art of all four series.  But I think unprofessionalism would be marked by inconsistency of style, not by choice of doing a particular style.  It’s like saying all rock drummers are amateurs because they don’t play jazz.  Or that songwriters are amateurs because they don’t compose serious symphonic music.  But I guess it’s easier to say something sucks than to try to figure out why you don’t like it.
