There is no need, it is literally pointless. TV shows are doing well (some more than others granted) so they don't need a ratings push from the movies and likewise the TV audience is so small it barely makes 8% of the movie audience based on a rough calculation, (BvS made $872,662,631 so assuming an average ticket price of 20$ that means roughly 43633132 people saw BvS, let's take Flash as an example it has on average 3.5million viewers that is barely 8% of BvS's audience) so the movies will serve no benefit from the crossovers either, not to mention do we really want to see CW actors go up against Affleck and co? Amell was pretty bad in TMNT from what I here.
