Leaving aside all my hate towards guest characters in general...
...Homelander was the only guest I was mildly interested in and curious on how NRS will translate him into the game. His persona is crazy, sociopathic, awkward and violent. Well, on paper - perfect fit for MK, at lest in some way.
But the outcome is... disappointing, to say the least.
- "Plastic" model that fits Injustice aesthetic more than MK; that may be only my feeling but there is something weird with guests this time in general. Like they are literally taken from the different game without putting this... don't really know how to call it... dirt? of MK world? Despite all my hate towards guests - MKX did it in a proper way at least. But I really don't want to elaborate more on that.
- bad animations. Seriously, this time I cannot be the only one that noticed it and as I'm checking this side I guess some of you see it too!
- Boring special moves. Counted 92384 laser-eye beams as: projectiles, regular moves and hits in strings.
- Lack of Starr's voice - that was expected, but still, not blaming the current voice actor, but that just feels weird
- Too much similiarity to Omni Man; for example - if we mix randomly the moveset, strings, launchers between those two - you wouldn't spot any differences on which move is designed particulary for which character
- 2nd fataility is boring AF; wasted potential
Ferra is the savior of this trailer. Literally every time where she is on screen something fun happens. The only missed opportunity is not to include Torr in the Fatality/Fatal Blow. But I'm not expecting any explanation from NRS why they left him out (lore-wise), as she is a kameo only and her whole presence might not be even canon to the current timeline. So it's a meh for me, but I can still live with that.
As a conclusion: Yes, I still hate guests and will never be an enthusiast of putting these guys - whoever it will be - to the game, instead of MK cast, but in this particular case it does not affect my opinion at all. I really wanted to give Homelander a chance, but from what I saw till now - not interested at all.
