I'm way more forgiving than I probably should be for the alt modes, I mean if the idea is to be in disguise a Formula-One racer kinda sticks out. And while I too am glad that his robot mode at least resembles Mirage (again not expecting 100% fidelity) he seems to have Jazz's personality. That's the double edged sword of keeping even some of the Bayverse continuity, I want Jazz back dammit. :/ Not Jazz in all but name.
Same with Wheeljack being a rally car (though a Volkswagen Minibus instead is a head scratcher, kinda thought he'd be a tow truck), but...why does his robot mode look like that. *shrugs*
