I watched Den-O those last two weeks, it was pretty good !

For once, I will make an exception and say the story in itself should be handwaved, it's not the main interest. As soon as time travel is invoked, it's very hard to write something solid (and previous season was Kabuto where IMHO writers also failed at this). In universe rules are not really convincing, not to mention plot holes and barely resolved stuff...

No, Den-O really shines with characters, comedy and visual jokes, they are gold there.

Now en route with Kiva. From the first episodes it looks like it tries to get darker and edgier. My fear is as it's been mainly written by Toshiki Inoue, his usual (and annoying) favorite story gimmicks will come in full force...
