7 out of 10
7 July 2013 | by (New Jersey) – See all my reviews

This is where people play follow the leader. This episode which I thought was great somehow got so much bad reviews by critics. And so I went to look at the reviews from the worst X files episode that I could remember, which was "Blood" and somehow people were giving it a B+. Anyway I thought Agua Mala could have described a few things better, like there was no way Mulder and Scully should have known (based off of what they shown us) that the fresh water is what keeps this creature at bay. I'm sure if you read this story written by David Amann , then you probably wouldn't have had that problem, it was the way they casted it. But I still must give this episode a 7 out of 10 because I really enjoyed it. It wasn't no classic episode, and it wasn't one of my favorites like "Kill Switch" or "Terms of Endearment", but all in all, it was good and enjoyable!
