I really appreciate this was posted and it gives me some thought of going out to buy the physical version. However, the quality of the uploaded pages is...mixed. I think this is largely due to the scans as some of the pages seem to cut off, which is bad when you're trying to read the excerpts.
Still, Prime is my favorite Transformers cartoon and I really appreciate this glimpse into the minds and production development of the creators. Say what you want about the Bay movies, but without them we wouldn't have gotten Prime and this new streamlined art-style.
