This show tried so hard to be everything but failed miserably. The first gaping plot hole is that there is absolutely no presence of any government authority in the show. Police? Hello?

Another thing, this show tries so hard on the romance, which turned out to be lackluster and hurried. Also, most of the love stories basically relied on "man saves woman, they fall in love" trope (which is such a sexist trope I can't even).

The show tried to be angst and edgy, but in the end, it turned out to be tacky. This is the type of show that deserves to be just a YA fiction rather than a full-blown series.

The reliance of plot twist without subtlety is crazy! Subtlety is key when creating plot twist. Plant a seed somewhere down the first half of the series in the most subtle way (on which it is barely noticed), and let it bloom during the second half. The screenwriters were probably just like...

"The second act is dragging, what should we do?"
"Let's just wing it. Pants in through. Add everything we can possibly think of!"

Also, the show gives off a premise to be a super fast-paced show, but it focuses too much on the boring parts. Some characters (especially the side characters) don't have proper motivations at all. The Gifted gave most of their characters good motivations (notice I'm using most since Ohm and the twins really did not have much motivation and Namtarn, Korn and Mon didn't really have the best motivations either. Pang's best friend had a good arc though) and I expect Blacklist to do the same, but failed horribly.
