Is Richie an underrated guitarist?

You know, I was just talking with my dad about this this morning. Richie is most definately underrated. Since there are a lot of people out there who simply hate Bon Jovi, they never really look deeper into the music and listen to a truly brilliant guitarist. As for the people who enjoy the hits really don't pay much attention to the guitar playing either (at least among the people I've talked to). However, people I have talked to who have listened to much of their music agree that Richie is one of the greatest guitarists to ever live. He is indeed underrated.

ah...
