I'm gonna gush a bit, so hold onto your hats. I promise that I'm normally a miserable bastard. I just legitimately like this place--that's the TL;DR version of the rest of this review.
I still remember the first few times I went into Fantasy. I walked in and thought "This is what a comic shop's supposed to look like". Trades across the wall, new issues prominently displayed, and a lot of floor space to back issues.
I expected, those first few times, to find the inevitable downside of "real" comics shops: the Comic Store Snob. Anybody who's been in more than a few comic shops, or seen the stereotypical "Comic Book Guy" knows the type.
But no! The guys at Fantasy have been consistently friendly and helpful, and have always made me feel welcome. Whether it's a stupid question like "Do you guys have X comic?" (Where X is literally right in front of me), or a favor like "Can you look up this comic, that I don't know the name of, that was published some time in the last millenium?", they always cheerfully help, and almost always find exactly what I'm looking for (and, frankly, the times they don't it's usually because I've described something so vaguely that nobody could).
I've been there when someone who obviously doesn't know anything about comics walks in. And I've watched--they offer help without being pushy, and are waiting for it to be accepted, because they all seem to legitimately enjoy helping folks find just the right thing, whatever it is.
It's a dumb thing, but I really appreciate that they've been kind enough to let me bring my dogs in--they're well-behaved, but it's not like every store's okay with it. I've had a subscription for (...does some math...) holy smokes, something like 6+ years? They've never judged what I wanted, whether it was everything Army Of Darkness related, or My Little Pony. They've never given me crap when my budget required I cut back from getting everything I wanted--and they've worked with me to make sure I stay in that budget and eventually GET what I want.
They know their customers well enough that they'll pull something for you in case you want it (and, thus far, they've batted 1000).
They've got back issues galore--and organized in fancy schmancy metal drawers. The outside may be plain (except for the sweet Batman mural), but the inside shows how much they care. They always get the best guests for the Tucson Comic Con (if that's the kind of thing you want to check out, seriously, check out their booth).
They've got a whole kids section, and play tables with toys. More than once that kid section's saved my bacon for presents for my younger brother or other kids. They've got posters and T-shirts and collectibles (Do I own every Flash thing? Yes, yes I do).
But I can't stress enough that the biggest plus of this place, over and above the selection of "all of the comics", is that they're welcoming. And not just that they've always made me feel welcome even though I'm annoying. They've made it a point to learn what my wife likes and pull that for her too--that's right, they're welcoming to GIRLS, too, as real people which, sad as it might be, isn't necessarily common.
No matter what you are, they want you to come in; it's not even that they don't care--it's that they do care, for you as a customer and as a person. Which sounds super sappy, but I don't care; when I got into an accident with my motorcycle, their concern was not "Yeah, but what are you buying", it was "Dude, are you okay?"
If you're looking for a comics place that's got everything and is going to treat you well, then Fantasy is the place to go. Say hi to Matt for me. And buy one of their sweet cloth bags. read more
