I didn't mind the new Hunters, but I was disappointed with the route they took at the end. They had this big buildup to how the previous generations heroes were needed, and then Taiki has to give Taigeru to ability to pull up the anticlimatic weapon that will save the world. Sorry, but while Taigeru was the series main character, he shouldn't have had to replace Taigeru at anything. He merely should have joined the final battle. It also would have been much more exciting to show all the characters fighting instead of letting them be absorbed.
There was only one area the final episode got right, and that was Baguramon being the old man. That was a twist I don't think anyone saw coming. It's a shame they couldn't have had more surprises spread throughout.
