After watching both episodes, I like it.... There's a few issues, like Dove's Feather cape that looks cheesy, they should of used something more high tech looking then soft looking feathers that deflect bullets.... They made Starfire look like a cheap hooker with those clothes... From what I can tell she has lots of money so I don't get the outfit at all... So there are some definite misfires on the show but overall it's pretty good, So far Robin and Raven are the standouts and the story arc so far is pretty good...
As for the costumes, yeah Robin's isn't to bad, I'm just glad they gave him pants instead of wearing green panties... but most TV show costumes are pretty bad.... I'm not a fan of the costumes in Arrow, Flash or Supergirl either...
