i agree with sammy_hunt 100%

This has been so consistent!... in getting worse and worse. While I watch this show week after week, I'm finding myself caring less about any character or plot point. They came off an incredible season 1 that had me almost in tears at the end. Season 2 was a complete mess that showed they didn't know who to make Zoom in the end so they took a punt and redid the villain of the season one story. Season 3, whilst its a touch better than 2, it is still inconsistent and they don't know how to do time travel at all.

They need to stop having crossovers all the time and have their seasons shortened by at least 5 episodes.

This is a harsh critique but comes from me wanting the show to be great because the 1st season was so good.
