This show feels extremely half-baked.

From the time-travel mechanics to other things, it feels as though the thought put into it was the bare minimum to allow story progression, but not enough for it to follow set rules.

It's like the mechanics constantly morph into whatever the plot needs.

Also, the main character is absolutely not my thing. Unless someone enjoys yelling at the screen in the same way that you do to the protagonist of a horror movie that is walking away from a serial killer instead of running.
