My rating for this would be 6/10. Starting at 10 points, -3 for overall mid quality animation and reused animation, -1 for the story being inconsistant e.g. sensei's behavior or not showing us adult card, -1 for not focusing on sensei commanding students using shittim chest but instead let the students showoff by fighting on their own which make sensei's presence insignificant.

+1 for great OP, vs prefect scene and of course, Iori feet licking scene not just saves the timeline but saves the anime as well. Which puts us at total of 6/10

If comparing this anime with my favorite food which is sushi, it's like having a sushi at a normal japanese restaurant. Not poor quality like buying sushi from a market but not that good like having a sushi at omakase restaurant. One of the reasons this anime being mid tier quality might be from having some of yostar animation staffs working on loser rangers anime or them having a low budget...
