Based on the reviews I thought that I was in for a treat. Alas, this is sub-par.
1. The plot always repeats itself season to season: Bad speedster pretends to be the good guy, threatens the whole world is defeated by the nerdy Flash team.
2. The same unlovable characters die and reappear as "multiverse" versions of themselves.
3. The storytelling is done in long tedious monologues for the "dumb audience".
4. The acting is mediocre.
5. The "special-effects" feel like they were done by VFX students and to make it worse they keep recycling them over and over again.
Overall, if you are a fan of the Flash comics you may like this, but otherwise is feels like a college level theater drama stretched out over a billion monotonous episodes.
