You have awesome animation, interesting set up, great characters... you have everything that made Mirai Nikki epic, but you wasted everything in rushed, pointless plot. The is a whole mess. Its fun to watch because of the points stated above, but it just doesnt work how it could.
Everything after episode 3 seems rushed. Some developments and character choices just didnt make any sense at any given moment. The original ending is overall stupid. Instead of just adapting whats on manga, they decided to make their own thing and its horrible. You keep watching, hoping that eventually one episode will glue all the pieces together, but it doesnt.
This anime would have needed at least 26 episodes to properly develop itself. But I guess our japanese friends were too desperate to jump on the "omg its another creation from the mirai nikki author" train and did this mess.
Dont hope for a second season. Your best hope is for an eventual remake in a couple years, hpefully it shall properly adapt the manga.
