Transformers 4 Review, it might get kinda spoiler-y but not too spoiler-y:
I fall in the camp of people who firmly disliked the previous trilogy of Transformers movies, but I supported their existence because I was a fan of the franchise and they brought in money and attention to the brand. Nonetheless, I will give an unbiased review here and I will start off by saying I think this one's better than the last three.
First of all, this was made for the fans. If you never liked any Transformers-related things in general, chances are you still won't. It's not for everyone. As a matter of fact, this whole film is product placement, so let's just get that out of the way. It's product placement that looks cool so don't come in here expecting some criterion collection shit. This isn't a movie review, it's a commercial review.
The improvements come in 3 forms: Characters, Dialogue, and Tone.
Characters: Shia Labeef and his crew aren't here anymore so there are new humans now. The new humans are more bearable and one of them, a Steve Jobs by another name, is actually entertaining. The dad takes the overprotective, "you-can't-date-mah-daughter-I'm-from-TEXAS" trope way too far. The Transformers get more screen time as well and are more visually distinguishable and have noticeably different personalities from one another. In previous films it was pretty much just Optimus and Bumblebee and a legion of grey 'bots who you couldn't tell apart. Also Dinobots show up near the end and they are undeniably awesome. Galvatron is voiced by Frank Welker finally so that's nice. Lockdown (a villain who first appeared in Animated) is the main antagonist though, so hopefully his deadlier, more powerful nature and his huge ship will carry over to other adaptations. This is what the movies are for really, to generate seeds(concepts) to be planted in good soil(other adaptations that will better flesh out and improve on said concepts). I just murdered that metaphor, but you know what I'm saying.
Dialogue: Better than the last three films because it's not just Shia screaming "OPTIMUUUUUUS!" Most of the critics hate that the 'bots got more lines, but most of the critics aren't fans of Transformers either so that's something to consider.
Tone: Age of Extinction wisely drops the more vulgar humor of previous installments. No longer must we hear about devastator's metal nutsack or robot pee. Instead it's fairly serious and when there's humor it isn't the cringe-inducing try-too-hard kind. It can be genuinely funny.
Overall: A vast improvement over the previous films. It's still an explosion fest (not a bad thing, but if you don't like that then this ain't for you)and thousands of humans certainly died in the crossfire, but it's faithful to the franchise and includes nods and respects the lore while adding new stuff. If you're a TF fan who hated the previous films, maybe watch this one and be pleasantly surprised, or at least feel neutral to the new trilogy. I don't like how the human-built transformers transform, though. It's kinda lazy in my opinion. The new Galvatron origin is interesting, and includes a nice nod to Animated. I'm amazed Michael Bay hasn't put in Unicron yet, but it makes sense. Once Unicron shows up you can't really top that sort of threat. Nonetheless, I have a feeling either Unicron, Primus, or the Quintessons will show up soon.
