I honestly didn't have a problem with Galvatron's transformation in the movie. It makes sense given the context that he's some kind of smart metal and shit.
What I did have a problem with was how everyone looked. They all looked like garbage. Detailed faces through large lips and an overabundance of folds and joint cuts look like shit and everyone suffered for it (Except Hound, I guess, since his "Rough and grizzled" look fit it). The robot modes went for a more smooth looking design, and as a result, they all looked nothing like what they transformed into (Sans Bee), and they just didn't do a good job in designing the bots overall.

Dinobots suffered from a lack of color, especially.

As for RID Grimlock, I love the guy. He's so silly but super vital to the team. I love when he's on screen.
