Will say, as an outsider who doesn't really care for Transformers too much, I think the marketing didn't really do much to appeal to anybody outside of hardcore Transformers fans. The only real hook was "they're animated! And Prime and Megatron are now friends I guess". It was already at a disadvantage being an animated movie, and there was nothing else for newcomers or casual fans to get excited over. I love Ninja Turtles, so I do have a bias, but Mutant Mayhem at least had the hook of having the turtles actually being voiced by and acting like modern-day teens, and a cooler, more creative art style. Didn't feel like there was anything fresh here for those not into the franchise like Bumblebee.
