So what's the point of having Mr.Terrific around if he's not doing anything terrific.
Also I'm willing to play devil's advocate for the filler episode that was Arrow, atrocious jobbing of Deathstroke, Darhk, and Merlin withstanding, in that it made for a better "For the Man who has everything" type episode than the one Supergirl introdued. If it wasn't blantant filler in a supposed big crossover even I think it would be better received: again jobbing of villains withstanding.
Other than that this crossover kind of sucks but Flash/Arrow vs the World was kind of interesting. It also does nothing to convince me that either Arrow or Supergirl are worth watching.
