Disappointing & bland.

Rating: 5/10 (14 March 2018)

I was fearing for this movie since I've watched the trailer. I didn't think the concepts presented would be explored in an interesting enough way. But as I saw a 7.6 on this movie's IMDb page, my hopes got up again, only to be crushed by the movie itself.
In Annihilation, you'll find:

Interesting concepts... but badly explored;
A group of female professionals... that make a ton of bad decisions;
A threat of unknown origin... unless you've watched the trailer;
Trippy, artistic photography... but the movie pace is very slow at times;

And several other examples of "this is good... but then this is bad", making this movie nothing more than a 5/10. Go watch a video of plot highlights instead, you'll get the same good bits without the bad ones.
