Well, he raised his family there, granted his kids have kids now, but i think he's liked it there.
Sprint built a huge campus there a few years ago.
As with anything, I'd suggest a trip to check things out. That's what they were going to do for us when we relocated, but as we grew up in the area, I passed and kept working (we worked together, and the company didn't know DH's trip was for a job interview).
My best friends sister and brother-in-law live in KC, and her parents just moved to Olathe I think last year.
They all seem to like it. You'll still find things like the musical season if you're into that. They have shopping and restaurants. It's just a matter of picking a town/neighborhood to live in.
For us, when we lived in Dallas, we got a map of the area, DH took a compass thing (like from math class) and drew a circle within X number of miles from the office as we wanted a short commute. We then looked at neighborhoods within that circle. We ended up in an older neighborhood and had a 10 minute drive to work not crossing or using any major highway or interstate.
Good luck!!
