These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Gundam 00: A Wakening of the Trailblazer
Broken Base: Diehard 00 fans will defend this movie with all the love they can. Many others, including most critics would rather leave it, than take it.
Crazy Awesome: Anything with Hallelujah is guaranteed to be this, but this time he gets GN Scissor Bits to play around with.
Crowning Moment Of Awesome: Basically everything in the movie, but especially when the 00 Qan[T] shows up and the Gundams and Braves absolutely unload on the ELS.
The 00 Qan[T] gets about five minutes of screen time but still manages to be even more of a blatant hax than 00 Raiser. Hell, 00 Qan[T] is compared to the Turn A as the most powerful mobile suit in the entire Gundam multiverse.
Ian's reaction to Mileina's confession to Tieria. Made better with Linda's AND Setsuna's response (implying a Shipper on Deck status).
Ian:(Upon hearing Mileina's confession over the intercom) WHAT DID SHE JUST SAY?!
Linda: Oh my; that's wonderful! Congrats on your new boyfriend.
(Setsuna floats towards the 00 Qan[T]'s cockpit, while letting off a light smile to Ian.)
Ian: This is no laughing matter!
Crowning Moment of Heartwarming: Setsuna returning to Marina in the epilogue, 50 years later, with his upgraded 00 Qan[T] standing in a sunny field full of flowers... itself covered in flowers.
The entire sequence from Setsuna waking up from his coma through to him launching in the 00 Qan[T], it begins with Feldt hugging Setsuna, who hugs her back (a rather telling action as he is usually rather protective of his personal space), Feldt then goes back to her post rather than follow the crews suggestion that she stay with him, when asked why she won't say says that she'll be able to feel his presence no matter where he is, and then offers a gentle smile right before he launches.
Mileina Vashti declaring her love for Tieria, regardless of his physical form, was one of the most heartwarming moment in the movie. People in the theater collectively went "d'aww!" and laughed at Ian's reaction following this moment.
Crowning Music of Awesome: All of the awesomeness in this movie is accompanied by equally awesome (and sometimes downright scary) music.
Kenji Kawai took at least three ("Trans-Am Raiser", "Masurao", "Fight") scores from the TV series, remixed them with a much larger orchestral group, and combined them together with vocal accompaniment (via One-Woman Wail and Ethereal Choir). The end result is called "Final Mission ~ Quantum Burst", and its not only eight minutes of pure concentrated awesome but also the movie's cue for the Meisters to hand the ELS their collective asses. If you somehow have yet to hear it unimpeded by the action going on when it's playing, stop doing yourself such a disfavor.
God-Mode Sue: The 00 Qan[T] probably would be this if it was used in any kind of military capacity. All the teething problems of the 00 Raiser have been ironed out, and the occasional instances when we see some measure of its power are impressive indeed. In fact, it's an arguable rival for the mighty ∀ Gundam as "most powerful mobile suit in the franchise", which is saying a lot in Gundam 00's relatively low-tech setting compared to Turn A's. As is, though, Setsuna is far more interested in using it for its primary purpose — a highly-advanced communications device.
Word of God posits that the Qan[T] is so powerful that it could have taken on the entire ELS force alone. And won. However, it was later clarified that this was ignoring several important factors, such as the pilot's stamina and counting out the regenerative ability of the ELS. Yes, the Qan[T] could have killed the entire ELS force... given two straight weeks of continuous battle, which no human being (Innovator or otherwise) would be capable of.
Hilarious in Hindsight: The super deformed omake that parodied the preview of season 2 stated the world would be invaded by aliens and that Setsuna would turn into Gundam for real. Did the writers accidentally spoil the movie?
Holy Shit Quotient: IF you can actually keep track of what's happening during the battles, your jaw will be on the floor the whole time. Even then, it's still mind-boggling how much action they managed to fit on the screen. Each battle tops the previous one in terms of sheer intensity.
Jerkass Woobie: Descartes Shaman, the Earth military's first recognized Innovator, is an arrogant jerk who is painfully aware that his superiors see him as nothing more than a living weapon. Kati's reaction when she first meets him is about as mixed as the audience's.
Narm: Several instances. For one, was the rotating shot of Setsuna's crotch while he was being Mind Raped by the ELSstrictly necessary?
Most likely, that was meant to be symbolic of a conflict taking place in Setsuna's core being, which in many Eastern philosophies is believed to exist at the navel.
Setsuna's appearance in the postcredits scene is really hard to take seriously.
Nightmare Fuel: What happens to those being assimilated is unpleasant.
Case in point: If you look closely you can actually see blood on the crystals passing through the skin.
Visual Effects of Awesome: The whole movie's animation quality is the best in the Gundam franchise yet, and the battles among the best choreographed ever. Special mention, however, must be given to the flashback of the ELS' origins.
So far, only Gundam Unicorn has ever come close (or at some scenes, surpassed) it in terms of visual effects.
Or, hey, even "Gundam meets Enderís Game, what with the aliens being unable to understand the individuality/sentience of humankind and the hero traversing time and space to communicate with them and then return years later, nowhere near the age he should be.
The Woobie: Saji and Louise may have settled down, but they're still having a rough time of it.
