This was a rollercoaster of a season. Not in storytelling but just quality.
For every good episode there'd be at least one if not two bad ones. I love how they keep trying to stop him despite the fact he has calculated for everything and knows all the outcomes. So why was he defeated at the end? As the resurrected hologram Thinker he outright states he had planned on and predicted her betrayal and them standing like that so he still hasn't lost. So she just unplugs him and poof. Over. How did he not plan for that...
Furthermore, this is the first season to get their time travel all screwy and wrong. You know from Season 3 they get past the Thinker as Savitar comments on it. You know they live and have kids based on their daughter showing up repeatedly which there was nothing subtle about that being who she was. So where are the the stakes for this season?
The first two seasons were fantastic and while the third season was a dip in quality it was still worth tuning in and never really felt let down for doing such. This season...ugh...Season 4 Episode 5 "Girl's Night Out" is probably the epitome of where this show was going wrong. Fun one off comedy episodes are fine when written well. This wasn't. The whole time I was watching all I could think was "when did this become Supergirl?"
