The Flash (2014 TV Series) and Titans (2018 Series)

DC Superhero series.

The Flash

This nine season Arrowverse show follows Barry Allen (played by Grant Gustin), an individual gifted with super speed on his mission to protect his city and the ones he loves from all manner of bad guys. While it does start out strong each season becomes less polished with later episodes totally ignoring the Flash altogether and just focusing on the other members of his team. Why does the fastest man alive have a team? Well, because he (or the writers) continuously forget about his powers which is one of the most irritating aspects about the show (and the comics I'm guessing). Also, as his opponents are also usually speedsters the "speed battles" get really ridiculous later on... to the point of having light speed saber fights. Try it out and just drop it when it starts getting too silly for you is my recommendation.

Titans

Another show that lost polish as it progressed in its four season run. This one follows Dick Grayson (Brenton Thwaites) in a "much darker style" show as he gathers a group of super powered individuals and forges them into a team. It's actually ok when it remembers to be dark and violent as there is some cool fight choreo, but especially later on they seem to have lost that memo and the plot does feel like the writers now didn't know what to do with any of the characters other than "lets put so and so in, because it would be cool!?" Another one you can try out but just drop once it gets too stupid.
