Pathetic way to force fans to watch other shows
30 November 2017 | by perovic96See all my reviews

This is not the 1st time they are doing crossovers, but they went with 4 shows. Not everyone watch all of them, I couldn't care less for those "legends" of tomorrow, if they are so legendary why are they just a group of leftovers from other shows, or a Supergirl (who I find to be a feminist knockoff of Superman, I don't want the same thing twice).

They want to force people to watch other shows, but for me, the effect they got is making me give up the Flash and Arrow I watched so far. At least if it was with something cool like Constantine. Disappointed.
