Yep, although I won't specify what "creepy Adam" means or doesn't mean. I only observed, don't understand, it. It just...was a very weird, unusual vibe from him after all these seasons, underscored by how he loves to talk about her personal qualities--and maturity and sophistication supposedly beyond her years (I, too, don't see it)--rather than her singing. Where his focus really should be, particularly when she's already been eliminated and he's not making a sales pitch for votes anymore. I also thought Reagan now lacks the bubbliness she started with and I hope she'll get it back now that she doesn't have to do this. She also seemed kind of "over" Adam, when you might expect a kid her age to be, if anything, kind of star-struck, especially since she was clearly -his- favorite. Maybe she's just tired.
The Reagan/DeAndre thing just makes Adam's decline as a coach more obvious to me. I used to overlook his favoritism because I thought he made some interesting song choices (at least for singers he favored) and sometimes pushed people to do things musically that they didn't realize they could do. Now that his tired schtick with Blake isn't providing lighter moments...and his comments about performances aren't very insightful...and he was inexcusable re: DeAndre.... he really has outlasted his time on the show, imo.
And, while Blake is everybody's pal--coaches and singers--and always nice to everyone, keeping a friendly vibe in a "competition", he doesn't really bring much insight or musical knowledge at all, and I'm a little tired of that, too. He gets singers through somehow--this time it seems with very little reason for it re: Chris--but he doesn't bring much either. I don't mind Jennifer this season (so much less of the "We here at J-Hud productions!") and her chemistry with Kelly is nice, so they can stay. :)
re: McKenzie. Yes, she didn't have The Look that would have probably made her also The Winner. But she got remarkably far with the look that she -does- have. And, more to the point, talented as she is, it's not really just looks. Sometimes people have a charisma that pops through--it's rare--but can make a performer something special regardless of not being a "gorgeous" 20-something or "adorable/cute teen". She doesn't have that "It" factor either. So I think she did very well, considering (then again, I think she's very talented, but just listening to her without watching I never felt she clearly was head and shoulders above everyone else, week after week. So it's not like she was heavily penalized for not being gorgeous.
Three of the finalists are okay, even with their weaknesses. However, I really don't think Chris belongs there. Nice guy, but really not musically a stand out in anyway that I can see.
