First was pretty bad, 2nd was more faithful i think to the cartoon series but still was kinda bad. They just make the bots too mechanical when in the cartoon they looked much simpler which imo was better than what was made for the films.
If their gona make a 3rd film it best be with cybertron and maybe a live version of the original transformers cartoon film with Unicron which would be kinda cool.
Translating the original, and more basic designs would look pretty bland on the big screen tbh. I mean these things were designed to be sold as action figures, and to be drawn for animation, so they're going to be basic. It would look to much like something out of Toy Story. Granted it would be 'faithful' but it wouldn't sell as a big budget movie. One of the biggest selling points of Transformers i to make them look 'cool'. It's not the 80's anymore. But each to their own.
Trailer looks interesting, wondering where they're going with the story.
