Could be one and its great if Kira's world the "perfected utopia" world would be successfully attain if not only he was killedby Ryuk(Light was killed by Ryuk) and for Misa and Light's life maybe lived happily ever after after attain Light's goal of perfect utopia! and give the deathnote back to Ryuk aftermath the completion of his goal...I think it ended badly for all. Kira's world developing would have been excellent, and likewise it sucked that L had to die. But it is not uncommon in anime that a series does not end where you hope it would. I think it should have ended with episode 26, not because they ran out of steam but because then Misa and light could have lived happily ever after.
