I was thinking the other day about whether or not the general audience of people actually like ROTF. When I saw it with my uncle(who grew up watching G1) he enjoyed it very much but when I saw it with my friends(who know nothing about TFs) they thought it was bad but they loved the first film. I then started to think about what they would like about the first film that wasn't in the second. I think the reason why some people may prefer the first film is because there's that "awe" when you watch the robots transform and fight and you'll left wanting more. Whereas in the second it almost feels like they just throw all this action and transforming at you that it almost just feels boring. I think another reason is that the second movie goes into TF mythology a bit more and don't really explain anything about it like Energon. They never even state what Energon is they just start mentioning it. After the end of the first movie I wanted more, at the end of the second I had more than enough, and I think this is how many of the general moviegoers may have thought as well.
