ok so the other one is kinda long. Here's the short version.
Macdennis can be separated into 7 phases.
(S1-S4) - In these seasons the homoerotic undertones are treated as more of a bit.
(s5-s7)- 5 is Dennis' most thirsty season, he nearly adores Mac (not to say he doesn't try to control him or get irritated by him). Then, after Dee pointing out how gay they are getting, there's a big pullback. Dennis says no homo, Mac says definitely no homo, Dennis gets married and kicks Mac out, Dennis gets divorced so fast and lets Mac back into the apartment.
(s8-s9) Mac tries to kiss Dennis on the mouth out of nowhere. Mac and Dennis have monthly dinner dates. They wrestle naked in a shower, but the "wrestling" is more like a swaying embrace. Their apartment burns down.
(s10-s11)
Mac and Dennis live with Dee now. They have to take turns jacking off to the same creampie videos to get off now for some reason ( I don't know why people think they were doing it together because from what I can tell they weren't). They move into a house together and nearly kill each other.
(s12)
Mac and Dennis are back in their own apartment. Mac comes out for real. Mac gets Dennis a Valentines day present, causing him to tear up. Dennis leaves the state to go raise his secret son.
(s13-14 )
Dennis' angriest seasons, needs a hug badly. He comes back from north Dakota. Mac pines hard, tries desperately to do what Dennis wants him to, but Dennis just wants him to take control.
(s15-16)
Mac backs off. The power has flipped, and Dennis is slipping. Mac explores his identity.
(Mac/Dennis Jr., Mandy/Brian Jr.) -suburbs/double life
(Macdennis paired with married couple/gruesome twosome paired with father son duo) - Gets romantic
(MacDennis/Malcom and his dad)- celebrity booze *the parallel could also be dennis/frank malcolm/his dad instead*
Hugh Honey and Vic Vinegar- Pretended to be gay married realtors
Double life- Pretended to be in an emotional relationship to get Dennis out of having to be with Mandy romantically.
Johnny- Dennis Catfishes Mac into having an emotionally and sexually involved romantic relationship with his online alias.
