So I've been watching Season 6 from week to week and I haven't been impressed. It really does seem like the show has run out of steam (at least the first ten episodes). There have only been two really funny episodes (Episodes 11 and 12, the two most recent). Part of that is due to the fact much of the main cast has left, part of it is that the replacements aren't that funny (Frankie is the new straight man, apparently, and Elroy occasionally gets some good lines expertly delivered by Keith David, but its too little).
Also, I totally want them to do a reunion episode with the original cast members all coming back that explores a dimensional anomaly located at the corner of the table (by Pierce's old chair, where Frankie currently sits now) that gives the real reason for Troy, Shirley, and Pierce's disappearance: they were switched with other-dimensional physical clones.
Anyway, Episodes 11 and 12 were really funny, but the first ten were a bit tough to get through.
