Savitar is just...And the whole Mon-el arc is starting to piss me off. Why is it so hard to have all three be good, it's like one/two have to suffer for the other to be great. Next season will probably see Arrow suck ass, SG being great and Flash going through yet another mediocre season.
Because writing is extremely,
extremely hard, especially with the number of episodes they're expected to churn out and very few writers have 100% hit rates. How many shows do you know with perfect runs? Now take out the dramas with 13 or lower episodes and the comedies. You'll be left with zero, as far as I can think of.
Also the only two writers consistent among all the shows are Kreisberg and Berlanti, and Kreisberg is primarily Flash focused anyway and Berlanti doesn't really write, he just provides guidance. We assign quality judgements to individuals, but it's a big team process with so many moving cogs we don't see.
It's much easier for us to pinpoint flaws after the fact than actually do this shit lol. Also opinions are a thing. We're loving Legends and Arrow. If you're watching these shows as a fourteen year old girl, you're the one screaming "fuck Uncle Guggie!!!" right now.
