I dropped the LN after the the MC perfectly predicted and planed a war, for the SECOND time. That he did so isn't the problem, it's that the story isn't set up to make such an outcome interesting.
Type 1: If a MC is shown to have an anti-laser force field, and then uses it at the climax of the battle to win the day, most people would be fine with this.
Type 2: If the MC is NEVER shown to have an anti-laser force field, and then uses it (out of nowhere) at the climax of the battle to win the day, most people would NOT be ok with such writing.
This story follows the writing of type 2. The author knows what outcome he wants, but doesn't set it up in a way that is satisfying. The reader isn't giving enough information ahead of time to make the MC look smart, rather than just conveniently having everything go the MC's way. Basically the author isn't smart/talented enough to pull off the story he wants to tell.
@boag post is about right.
