Goodness me no.
It's bearable. Definitely aimed at kids, in the 4-8 bracket I think. Even on hard its a cake walk. I still play it occasionally, just to get all the collectables, and hear the voices. I'll never tire of Welker as Megatron.
It does have vehicle combat and the Transforming is handled well, you can drive and TF and attack, jump etc all in a smooth motion, which is what I really liked about the ROTF game on ps3.
I do like that their guns transform (Hold to charge and the weapons changes shape) and when in vehicle mode, if you shoot parts, of the vehicle transform to make the guns. EG, the side panels of Ratchet drop out a bit and reveal the guns, so there is some interesting stuff, but you can finish it pretty soon
