The only disagreement is, I didn't see anything about going simple.
When you are writing schlock, and the point of the story is it's Schlock, and you want the reader to have fun reading schlock, sometimes, you just come right out and say, "This is Schlock. Now buckle up, cause we gonna have some fun!"
Take I was summoned:
"So you are saying I was summoned by a supervillainess to another universe?"
What does this tell you? Everything you need to know. There is someone who has been summoned by a supervillainess to another universe. You know not to take this too seriously. The title and the opening line are virtually identical. There is no pretense. What you get is what you see on the label. Just relax and enjoy the ride.
I guess my point is, sometimes, don't overthink it and don't over sell it. You want the reader to know what they are getting into. They have many choices, make sure your choice doesn't fool the reader into thinking your story is something it isn't.
