The villain of this epic movie and he looks fantastic and sounds intimidating, the character feels very formidable. He is equipped with an fiery ax weapon that we see is launched towards Batman’s new toy--the Nightcrawler. Steppenwolf also seems to have an army at his disposal that has the young Justice League shook a bit. The character's voiceover/speech in the trailer was filled with truth, Earth in the grander scheme of things is very defenseless(“No Lanterns...No Kryptonian”)--making it an easy target for other worlds--war worlds.
2) Alfred Pennyworth:
It is an absolute pleasure seeing this rendition of the classic character portrayed by Jeremy Irons. He is easily the most active of the Alfreds seen on the big screen at least and his comedic banter in the trailer is a much needed break from the League’s dark task of fighting an alien invasion. His interaction with Batman is to be expected,he helps engineer Batman’s vehicles, but when he interacts with Cyborg in the trailer it is comedic gold. It is also good to see Cyborg have a small quip in one of these trailers.
1) Superman Tease:
This part of the trailer was done very well and once again used Alfred in a surprising way. The producers chose right not to show any glimpse of Superman--save that for the movie. It looks like they are learning from their mistakes from Batman v Superman and not showing too much of the climax of the film. Audiences know Superman is coming back in some shape or form but it adds a bit of suspense to the movie if they save the reveal for the day of release and not spoil it in trailers or even photos.
