- The Constant Start and Stop of Meggy's development (seriously, it ended with the Anime Arc, ended again a month later, was restarted and stopped again in Meggy's Destiny and has finally ended with Meggy moving into the kingdom. Reach a damned conclusion!)

- The Rapper Bob arc. Fuck that arc. It served no purpose and didn't need to happen

- The Anime Arc. It went on way past its end and started Meggys downfall into uselessness

- The fact that Luke and Kevin have fallen into reusing concepts and the same jokes over and over. Like:
2011 - 2016: Well thought out episode with jokes that land and unique concepts like Mario Simulator.
2017 - Onwards: hee hoo beeg smg4, Mario fat, Toad is an ass, seiko is a pun, corn, Mr Hall, dead memes, etc

- Most new episodes are either not funny, based on a dead or bad meme or just straight up a poor remake of another episode like The Totally Legit Leaning Show is just a Remake of Mario Preschool from two years ago.

- Long SMG4. That's it.

- The fact that pretty much all side series' that have been made for SMG4 has been forgotten (What if Mario was in, Guards'n'Retards, Wacky Wario Bros, Literally everything about theawsomemario channel, Meet The Cast, etc)

- The fact that most of the videos are just filler for the inevitable 5th Arc (yes. Fifth. The Mushroom Wars Arc happened.)

- Most, if not, all side characters have been shafted for the same team (baring a couple of instances of Steve, Axel and a few others) of Mario, Meggy, Bob, Boopkins, Mr.Halls and (rarely) SMG4 himself. (seriously, what does SMG4 contribute anymore in universe other than to be the 5th straight man to the red bumbling paisano Mario.)

- Where the fuck is SMG3? In fact, what happened to SMG2 or SMG1? They appeared for one episode each and then POOF! Never seen again!

- Almost every character has been reduced to one joke.
Mario and Swagmaster are dumb
Toad and Bob are dicks
Seiko is a pcycho
Tari, Meggy, SMG4, Chris, etc are the level headed ones
Luigi is a coward
Peach sucks
Axel is a fuckin WEEB
The Tellytubbies... Well actually they just do what they want to
Bowser is useless
Mr.Halls hates everything Illegal
Boopkins is a punching bag
The list goes on.

- The tone is incredibly inconsistent. You get the end of the Anime Arc and then suddenly: MaRiO wOrKs At McDoNaLdS.
Like, are you fucking kidding me!

- tari deserves better. That's not even a complaint, Tari just needs better friends than Mario.
