I think the point some people are missing or just not trying to take into consideration is that since the G1 Cartoon there has barely been a Prime (or any other character for that matter) that looked anything like the original truck/vehicles save for the Beast Wars tie in episodes in the end of season 2/beginning of 3.
It's progression. Is it (and I swear to Christ I hate this term) raping our childhoods? Yeah. Blatantly. But as the same time it's progressiing into the future of things.
Yeah. It's going to be (literal) movie magic and...oh noes...science fiction fantasy in a movie about somehting a lot of know, love and cherish but at the time it's something a lot of us have wanted for a long time.
Let's just ALL hope it ends up having a decent story, setting, acting etc so maybe it will come out on top and we can hope for improvements in the future.
Just give it a chance. After you see it, by all means, rip it to shreds but man, some of you guys need to take a break.
