Hammerman 

One of the worst piece of Celebrity media I've ever seen (only being tied with Logan Paul's airplane knockoff) Hammerman can even barely count as animation since it animates at 2 frames a second. Even the show tries to delay the embarrasing cartoon with live action fluff and an incredibly long intro. It felt like MC Hammer was forced to be apart of this at gunpoint. 

Rick and Morty anime

A show that not even die hard R&M fans can defend.. horrible pacing, dry and bad voice acting (seriously you can tell how bored the VA's are), new Morty girlfriend plot that isn't interesting, tries to tell a more serious story compared to silly regular R&M, but it doesn't land and is incoherent, tries to have less humor than the show but the jokes they try to tell are painfully unfunny. Overall a total flop that lasted 1 season and is pretty much negatively recieved by the fanbase (aside from the 3 fans of the anime) and the anime artstyle doesn't translate well and ends up looking like a poorer version of the base show. To Be fair, the shorts on youtube were better recieved but this was just piss poor. Lets hope the President spinoff is an apology for this. 

Kentoshi 

This sorry excuse for animation, much like Hammerman animates at 2 frames a second. For a boxing anime that is a disgrace! Even Flip o rama from Captain Underpants has more animation. has terrible voice acting, contains so much real life stock footage, and rocky references that you'd ask yourself "why am I not just watching Rocky instead?" This ova came out in 1990, yet looks like it came out in the 70s. A completely unwatchable anime that not even Japan wants.. im pretty sure you can get a sealed copy of this on Japan sites for free if you asked.. this anime is so boring and generic that the title translates to Boxer..

"Seriously why was this even made??"
