The so this came out of the Man of Steel mini that I did read and I have to say that I found it to be WAY out of character for any parent to allow their child to go with someone who their last interaction with was adversarial. Superman saw how Jor El was disputing the Oz effect. He knew he wasn’t behaving ina manner that was consistent with what he knew from his records, papers, and even times spent time traveling and meeting him. He knew Oz had kryptonite lodged in his eye which it would be safe to assume would cause some sort of issue and based off of the behavioral issues, that would probably be mental. Also, Lois and Clark may end up in a lot of crazy situations but prior to this instance, I wouldn’t say they were irresponsible parents by any means. So, I think them letting Jon head out into space with Jor El after he’d already been acting crazy was definitely out of character and probably one of the most forced things I’ve seen in comics in a long time.
Now, all that being said, I’m trying to look past it and enjoy the Superman titles. There are problems that I hope eventually get worked out but I do have concerns going in and this poor handling of the superfamily was a huge reason for my trepidation going into the on goings.
