This guy does a great job explaining why the whole "Martha" scene isn't as dumb as everyone thinks it was.
I thought it was obvious what was happening in the scene, his description is what I thought it was. The scene fails in part because him calling his mother "Martha" was an obvious writer contrivance (who calls their mother by their first name? Especially when it's already established he calls her mom/mother) for the sake of easy comparison of the two characters backstory, and thus felt phony. Not to mention the abrupt transition after this with Batman and Supes teaming up as though nothing happened is poorly handled, as though nothing happened.
Of course, that scene is a minor problem (focused on way too much by online critics) in a bad film, one that fails in most scenes from beginning to end.
But hey, at least it was better than Suicide Squad.
