I admit I don't read a lot of graphic novels, but I happen to fell in love for some of them from the plot, that is too interesting to miss. The Mythics is one of them.
As the beginning of a series it is good, the drawings are generally well made and I like it to be divided into three mini-stories with different MC, which present the various heroes of the saga. My favorite is without doubt Abigail!

I found, however, that it was a bit slow with regard to the scientific explanations on which it focuses in the first part, and that instead it proceeded too quickly in the unfolding of the events, which are repetitive:
(SPOILER)
.
.
.
... in fact the structure is the same for all three parts: the hero discovers the powers / has an encounter with the antagonist in which he-she loses / finds the weapon destined to him-her / defeats the antagonist / the antagonist will return.
.
.
.
I found it repetitive and honestly those that should be plot twist fall flat and you can already predict them pages before. But the general imagination for the setting and the features is very good so it recovers.

I don't know if I will continue the series, and if I do it will be mainly for Abigail.
