I'm a staunch defender of ROTF, but it has to be said that the Pretender concept was a bad choice overall. I mean, in theory it sounds great: an external armour shell of an organic mode, used to hide the inner Cybertronian body - the next step in evolution for Cybertronian lifeforms/warfare (Pretender - Transformers Wiki). In practice, it came off as the Decepticons' pet T-X/XJ9, a hot alien teenage robot sent to find out all about Sam, doing all sorts of tricks (straddling Sam, using her tongue probe). Not only did it NOT work out, but it raises issues: - why could Bumblebee not warn Sam she was a Decepticon? I mean properly, like warning "Sam, she's a con!" or showing on a monitor her robotic nature, not spraying her with antifreeze or bumping her head (alternately it looks like he didn't want Sam to cheat on Mikaela or was jealous of Sam or something) - if a Decepticon could take on an organic/techno-organic mode, doesn't it stand to reason that others could too? Wouldn't that have been an interesting thing to see? (I earlier made a thread about beast modes) - and couldn't Dylan have been a Pretender as well? Just stick him down on Earth in the 1960s, make him a machine/man hybrid with a desire for Carly, and also who has nothing left since he cannot be neither human nor Con. Something interesting like that. They could have removed the Pretender angle, have Ravage sneak around the college and attack Sam (like what Laserbeak attempted in DOTM), and it would have made no difference at all.
