Review Detail of Xenoblubber in Viserys Targaryen with a system (SI)

Started out really good, but the longer I read the worse it got. Story is filled with irrational decisions and actions taken by the MC with little explanation or reason behind them. For instance, the MC builds up a power base in Essos but after an assassination attempt (wasn't even the first, but I guess this attempt was 'special' or something), he freaks out, packs up, and decides to hide in Dorne where he doesn't have the support of his massive army to guard him or his sister. The author does this for little other reason other than him wanting the MC to be in Westeros to 'watch the books plot unfold with his own eyes'... Its just one of the many plot points the author forces to happen in this not-thought-out-at-all story...
