I tend to feel like MMK takes it too far with the "inspired by" looks. It's one thing for brands to make bags that are similar shapes - there are only so many ways to make a bag. It's another thing entirely for a brand to make a bag that matches shape, material, color way, *and* embellishments of another designer's bag that just happens to be popular this season. I can't scroll through Michael Kors bag selections without thinking "oh, that's a knockoff of the Neverfull, there's a knockoff of the Sac du Jour" - the bags are just too recognizable as imitations of more expensive designer bags. Other contemporary brands -
Coach, Kate Spade, etc. might make bags that are similar, but they put enough of their own stamp on the bags that I can look at them and think "that's a Coach bag," instead of "that's an MMK knock-off of _____."
To be fair, other people consider that a feature. People will recommend MMK bags on the basis of "this one is like the Chanel flap, but much less expensive," etc. There's nothing necessarily wrong with going with a less expensive, similar-style bag, from a legitimate design house. It's certainly better than buying out-and-out fakes. It might even be a good idea to try a style of bag in the $200-300 version before you shell out thousands for a bag that might not actually fit your lifestyle. It's just not to my taste.
Getting past that, I just haven't been that impressed with Michael Kors bags in person either. They just don't speak to me enough to want to buy them - the materials, colors, styles have been fairly bland at the price points that I shop at. There have been some Michael Kors Collection pieces that were quite nice, but that's entering a luxury price point that's out of my range.
All in all, though - I'd much rather someone buy a real MMK bag than a fake LV or YSL or whatever. And most people who aren't bag nerds won't notice that a bag is a derivative design. Most people I know think it's outlandish to spend $200 on a bag - $2000+ is downright insane by that standard. I think I'd get chased out of my family if I ever showed up carrying a really expensive luxury bag, lol.
