-Out of the bat, I would say that, they made an amazing job at giving us little peeks of other earths and the future, gadgets and props they use, look really good. Shout outs to the team that made the props.
-A relationship between parents and their children, they 90% nailed this department.
-Ralph is a pretty good addition to the dynamic of the group they call "family". He's the perfect portrait of a friend.
-CGI and 3D work, is pretty damn good. Bravo!!
-Uninteresting story of Cicada and his niece. All about this plot is incredibly bad and dull. And to top this, Cicada its basically the main villain of this season.
-I should stress out this a little bit more. The antagonists and their reasons to do what they do, is just incredibly hard to watch, specially the point of view of the niece.
-The actor playing Cicada, is possibly one of the worst actors to play a villain. His voice, his face and the script he had to work with were baaaaaad!!
-Talking about acting; secondary characters, mostly meta-human villains were also weak when performing at this season.
-Flash's daughter should be tagged as the villain of this season. Not because she's actually the bad guy on this, but because everything surrounding her character, is so badly written, her lines, her attitude towards problems and the main conflict, her way of victimizing herself in order to get what she wants from everyone, she has the classic attitude of teenagers on teen flicks "I KNOW BETTER THAN ANY OTHER PERSON AND EVERYONE IS STUPID" type(she's on her early 20's btw).
-POLITICS. Following the Hollywood politic agenda, they gave a "twist" of some of the topics of today. This time was PRO-CHOICE(? or something like that). basically asking the person if he wants a procedure or not, regardless if this procedure could end up saving someone from the team while in combat. Still have the full diversity of races from previous seasons and women empowerment.
This season, was pretty much a filler. Might as well call it a non-canon from the TheCW version of flash. Everything about the story/plot feels forced, dull and unnecessary, specially Cicada.
