Saw it last night (ha) at 8:30 and didn't get back until midnight, so didn't bother posting.
I loved it. My dad however, not so much. What we have is a conundrum. Everyone complained about the previous movies that they plots were paper-thin and were just excuses for explosions. Now, they've added a plot and lore. And now everyone that isn't a die-hard Transformers fan will be incredibly lost like my dad was.
For people that know their Transformers, I think it's a good movie. For those that don't, well, I can see why critics are bashing it because I can understand them being lost by the plot. This wasn't a movie for general audiences. It was a love-letter to Transformers fans with robots that had personalities, a plot straight out of one of the TV shows, and lots of lore to boot.
The movie does have it's issues though. For instance, it does feel like two movies in one. AoE suffered because it was too long. Several scenes could have been trimmed to help fix that nearly insufferable three hour runtime, but it was a cohesive story. The Last Knight really felt as though it was two movies combined, and that's the major thing I think is wrong with it. TF5 should have either been the Autobots on the run and introducing new characters Izzy & Sqweeks, OR been the Knight plot. Not both. Izzy and Sqweeks disappear after the first third of the movie, and it becomes completely different after that. Still, for what we got, I feel like Bay did a good job with what he was given.
I loved that almost all the robots had personalities, and am excited that those that had limited screen time at least got one line a piece. The days of Jolt standing in the background and going poof are thankfully behind us. I'll always find it weird that the movies don't push the voice talent. Shouldn't the fact that Ken Wantanabe, John Goodman, Steve Bushemi, and the butler from Downtan Abbey are in this film voicing Transformers be something to advertise? Oh well, I'm not the marketing department.
Overall, I really enjoyed it and am excited for TF6 (and cautiously optimistic for the Bumblebee film).
