Oh no... I would almost say it's a fanfic given how much stuff it appears to rip off from.
1. Yamcha pose? Really? The first thing you do for the first trailer, is take Superman out, not in any other fashion, but you leave them with the Yamcha position?
2. David looks wrong sadly for the role. The moment he grabs onto Pa Kent, I can't tell what emotion they're trying to convey. Might be better in film, but for trailer, that ambiguity is not what you want to present.
3. You can tell David can't whistle. It doesn't look like whistling at all. Not only that, but to whistle you really need to have your ability to breath, and not too long ago, they had just been wheezing hard after being trounced by whatever. So it's kinda unbelievable that they can suddently whistle for Krypto. Also, that string of blood from David's lips continues to "not move" whilst Superman is whistling so loudly. We all know Superman defies physics, but if that's the case, maybe that's why David's Superman doesn't look like he's moving when he's flying through the air in his poster?
4. Krypto was nothing special thus far.
5. Superman rushing in to save the girl looked good however. Although it looks to be PIS, as the girl very clearly had this HUGE monster behind them, so unless if they're deaf, they should have known about it behind them and didn't need Superman to save them. And most people with such disabilities are often way more aware of what's going on around them precisely because they know how dangerous it can be for them.
6. Another Superman based actor (Nicholas Hoult) there auditioning to play 007 I see.
7. Not sure what's with Superman inside a glass box and needing to break out, Brainiac capture? Or by others? Seems weird, as we do see others there with them in other cages.
8. Obligatory tiny kid raising the Hero standard and asking to be saved - a faux pax by Gunn, you don't bring stuff like this into the Superman movie, because it can only end up in one way story wise and it ends up killing any type of story you can write later on, because Superman absolutely can resolve it unless if they can't. In which case, they're not Superman... Not rocket science.
9. Batman v Superman: Dawn of Justice - Remake.
10. No honestly, it is, not only that, some Man of Steel remakes too. Nolan Batman too if my eyes aren't deceiving me. It's literally pulling scenes from all over the place.
11. And of course, Superman's suit throughout the trailer, remains as we thought it would be, mostly tidied up, but still lumpy/bunched up in areas that clearly shouldn't be to show off a Superman physique.
If you were to have told me this was one of those fake Trailers often made, I might have believed you to be honest. That Yamcha pose...
