The first two seasons of the Flash were above-average. They captured a goofy superhero and the Silver-Age bogus science. Most of the characters were well-rounded and sympathetic. Despite this, already early on there were many cracks in the fabric. I am a fan of a lot of cheesiness and camp, and that's one reason I felt that the 90s Spider-Man cartoon is still watchable. However, the Flash has a lot of missteps in its cheese department, being hammy or eye-roll-inducing (in a bad way) instead of pleasant or entertaining. The Flash spends only about 40% of the show doing actual superhero action, and there's a lot of inconsistencies in his abilities. The melodrama was endurable, but not especially enjoyable, and the "surprise villains" were very predictable. The two seasons ended relatively the same way, on some kind of pseudo-cliffhanger, and, of course, a lot of running.
Season 3 doubled-down on everything wrong with the show, and despite the broad library of Flash comics they could have drawn from, a lot of the season was rehash of things we had already seen. The villain was basically copy-pasted from the other two seasons with a senseless twist that doesn't really have any emotional weight. The melodrama was dialed up to 11, some actually likable characters became jerks for basically no reason, there were tired side-plots, and it was a long slog to get through. I would give that season a 4.
The show goes on, so I hope it gets better, but I am not especially optimistic.
One last thing SPOILER: in season 3, Savitar tricks a character to trade places with him in his prison. Why did he feel the need to trick that character into his plan when he could have just used the Rival? I really can't get over that.
