My main complaint with the first season was that the chronology was all jumble, to the point that it didn't make any sense until the latter episodes. Also, some of the practical effects were beyond bad. But apart from that, I found it quite enjoyable.

As for the second season, it still feels jumbled even though it's mostly chronological. It's as if the show runners couldn't descide on wether the show is episodical or continuous, nor what the common thread of the season is. As it stands, more than fifty percent of the scenes feel out of place and out of context. Possibly the show runners thought this would create an epic feel, but sadly it doesn't. More of an amature feel.

Henry Cavill and Freya Allen is a great cast though. Sadly they're not enough to save the show from itself.
