I’m not pretty sure about the first trailer of Shadowhunters tv show. I’ve many doubts about scenes such us:

1) Jocelyn tries to warn Clary (When? Why?) and then makes her  to disappear (it seems like a bidibidibodibibu scene).

2) The casual meeting between Clary and Magnus in the Pandemonium club (I guess it’s where they are in that scene)

3)The rune on the birthday cake

4)Clary kills the demon in Pandemonium, not Jace (Again: why?)

5)The angelic swords seem more like laser swords from star wars.

Despite these points I really liked the chemistry between Jace and Clary, the locations and the lines (I think they clearly understood the characters).
