I have watched all of and only season 1. This will not be a balanced review, but instead, i will mostly warn you not to watch (most of) the season and give my reasons for that.

I recommend watching episodes 1 and 2 and skipping the rest of the season. The first two episodes were amazing. They were so good! The premise is amazing too.

The rest of the season is plagued with first: very many slow, unnecessary, predictable and uninteresting scenes. While the first two episodes were packed full of story, the rest of the season had many to me uninteresting minor character specific conflicts, a predictable main conflict, and was overall lacking story (that impresses).

Second, the season is abundant with many of the characters making dumb or unintelligent decisions, which made the story harder for me to believe and left me frustrated many times.

You might decide to watch the whole show anyway because: you like superheroes using superpowers. Well: the characters do not act like heroes, and you won't get to enjoy seeing powers used in interesting ways. Maybe you like to watch a team of superheroes: well, the characters unfortunately don't act as a team for a big part of the season. Maybe you like the theme of time travel: well, there is nothing interesting about the way time travel is used in the story. It is mostly used as a plot device, so I would not call this a story about time travel or a time travel story. Maybe you like the idea of exploring what it is like to live a regular life while having superpowers: While this topic is being touched, I do not think this is what the story is about.

They could have done so much more and so very different things given the powerful premise. I was hoping the show would surprise me and reward me with a great conclusion of the season, but the show does not substantially improve in its final part. I still give the show a 7 for a great premise, for the excellent first two episodes, and for a couple of figuratively beautiful scenes, including at least one in the final episode.
