This is what I hate the most about these trashy revenge isekai. Evil characters are just over the top evil and stupid that it's hard to take them seriously. A real good revenge story has realistic villains with understandable motive and intelligent approach to wronging the MC.
Another thing is that these revenge isekai mostly focus on how the MC torture his enemy after getting the upper hand, so it becomes boring fast. The meat of the story should be how you topple all those bad guys from their position of power through meticulous planning and intricate plots.
Yes, I know I'm asking too much from the isekai genre, but it shouldn't be too hard to copy from The Count of Monte Cristo.
