    My theory is that AP bio is Denises new life that he started after leaving Paddys pub at the end of that one season. So we all know it’s going in soon because he showed back up to the bar. Also The Mick was finally Dee’s big acting break but unfortunately she fucked it up and it got canceled. Next season she’s going to either live in a fantasy where she’s trying to get to show up again or she will be like depressed Dee a few seasons ago. It all makes sense in my head and that’s what I’m sticking with because it makes everything so awesome.

    I'm still waiting for Glenn Howerton to come out and *admit* that there is _a problem_
    _A problem_ that he doesn't have an answer to.
    Glenn Howerton, when are you going to own up to the fact that *you* and *you alone* are the man responsible for the state of Fallout 76, and that you can't P.T. Barnum your way away from this catastrophe?

    Glenn's new show kinda sucks . Glenn's character is the ONLY funny character , everyone else noticeably SUCKS . Its a shame too , because Glenn seems confident and passionate about the show , and its even more of a shame , because he is really good in that show , but brought down by every other aspect .

  • Rupert Murdoch
    Rupert Murdoch 8 months ago

    I''ve watched every episode at least 10000000000000 times and the only 100% fact about their writing is they do not think ahead, they come up with this stuff on the spot and don't have some "master plan" buried deep that takes 20 seasons to figure out. If you had told Rob in season 2 that at one point he would put on 50 pounds of fat for a season, then do TRT and come back the next season looking like Dolph Lundgren, he would have laughed in your face. They do not plan this stuff out ahead of time. This isn't "lost", its Seinfeld. If anything, they are doing this so that they very final episode when they go off air, they can do a "courtroom" thing like Seinfeld and get them thrown in jail.

    • Jt Money
      Jt Money 3 months ago

      Rupert Murdoch Not entirely true nor false. The weight stuff and other things come with time and maturation of the show but they do plan ahead. The character growth, and how that’s represented on screen, has been planned since the beginning.

    I very badly wanted Jack Griffin to be what Dennis actually left and became in season 12. He murdered an almost perfect look alike much like Wendell Albright. He then takes over jacks life to get off once again then spirals downward learning very quickly he wasn’t cut out to be Jack

    Anybody watch the new season first 2 episodes doesn't it seem like they aren't even trying anymore it's not that funny #1 mac is built now. #2 dennis seems less narcissistic and sociopathic. 3# Dee seems less well bird like. Charlie seems the same pretty much though and Frank has even stopped dying his hair black.
    Well I guess it's the writing too.
    I hope it improves because this was my favorite comedy show.

    • Jt Money
      Jt Money 3 months ago

      rocky dennis lmfao 1. Mac being ripped is hilarious. Shows what he was capable of once he let go the burden of being in the closet. Complete opposite of what happened when he hit rock bottom. 2. No freaking way. The hell are you talking about? He’s even more off the rocker because he’s trying to be “normal” and that’s just scary thinking of someone like him forcing himself to be that way. It’s like pouring gas on an oil fire. 3. Sure, okay.
      The writing is one of the strongest parts of this season as we’re finally starting to the gang reap what they sow. You have to get your head out of your ass.

    Dennis is a serial killer who framed Dee's neighbor in season one by placing the heads of his victims in the freezer. In CharDee MacDennis 2: Electric Boogaloo, Dennis sculpts out a womans head, saying that her head being frozen was his idea of what everlasting love was supposed to be. Think about it 🤔
