I mean i want to watch transformers 3, do i have to watch 1 and 2 to enjoy the film ?
3 does relate to 1 and 2 No, not really but it helps to watch the prequels. I understood 2 without having to watch 1. The only thing I don't understand is why Bumblebee's vehicle mode license plate is different from his robot mode plate?
Yes, Transformers: Dark of the Moon follows Transformers and Transformers: Revenge of the Fallen. I don't think the story's so complex that you won't be able to follow it, but I would recommend watching the first two films if you have the time.
