It's very well made, top notch effects and acting, but if you ask me at the end of most episodes what exactly happened, I honestly can not tell you.

After the praised season 2 finale, I still have no idea what happened and why. Maybe I think I know after watching loads of ending-explained-videos after almost every episode, but honestly, if a series or movie needs that much homework it's not worth watching. I became very frustrated with the first season and started watching it allover. It helped, but not doing this with every season or episode. Too much timeslipping for me.

Again, loads of cool stuff going on, great scenes, but just way too difficult stuff for the average viewer.
