This fandom has a wide variety of opinions about the movies. That's fine, and I get that. What I don't get is fans who say the movie(s) they don't like are not Transformers, when in actuality they ALL are EQUALLY Transformers movies. The 2007 movie has two warring factions of Transformers coming to Earth and fighting over the Allspark. Revenge of the Fallen has an evil Transformer come to Earth and try to destroy the Sun, and other Transformers try to stop them. Dark of the Moon has a ship full of Transformers that crashed on the Moon, and one of these Transformers' allies revive him, only for the newly revived Transformer to reveal he's been working with the evil Transformers. Age of Extinction has the good Transformers in hiding from a bounty hunter Transformer who is working with bad humans, and the remains of the good Transformers are being melted down by humans to make their own Transformers, and these humans are being manipulated by the head of a decapitated Transformer with evil intentions. In The Last Knight there are these ancient Knight Transformers, and they're enemies with this deceptive Transformer who has various Transformer minions and wants to restore Cybertron by draining Earth's energy, and the Earth happens to be a giant Transformer. The upcoming Bumblebee movie has a friendly, yellow Transformer who talks through the radio, and there are a couple other bad Transformers. You can like or dislike any of the movies as you choose, but every single one of the movies are equally Transformers movies. They all feature transforming, sentient, sapient, alien robots form Cybertron. They all feature Autobots and Decepticons and sometimes other Transformers, like Lockdown, Allspark Mutations, and Infernocus. All of them so far are inspired by stories and concepts from G1 with some other iterations mixed in. It's fine to have preferences. It's not fine to determine what is and isn't "true" Transformers, when all of it is. There's plenty of room in the brand for everyone to enjoy what they enjoy and allow others to enjoy what they like. One fan's "ruined forever" is another fan's G1.
