I haven't seen the Season 7 eps yet... probably won't until it comes out on DVD. I never really thought the show fell off, though. Just had some low points, like nearly any show. Season 4 was my favorite, and I loved Season 5, up until the anti-climactic end. Seasons 3 and 6 were the low points in my mind, but I'm hoping 7 will change that. Looks promising.
