They're Watching isn't bad, but isn't good either. It's a good time-waster. A movie about a small film crew doing a special in a small Romanian town full of superstitious and suspicious people, it starts off quite good with the only exception that one of the characters tries WAY too hard to be the stereotypical annoying smart-mouthed guy that everyone wants to see die. I mean, he's so unbelievably annoying and unrealistic that I almost had to shut it off.
But I endured, because the rest was pretty good. Things start picking up, the movie's paced fairly well, interesting stuff happens, there's an obvious and passable storyline, but then goes to cheese-town at the end. An over-abundance of cheap CGI effects, does not a good horror, make. Leave that to the Sharknados of the cinema world. Watching this movie was like watching an expensive firework fountain put on a good show for 30 seconds, then when things start to look like it's heading into its finale, it turns into a large snake (look up snake firework in case you're unfamiliar with the worst firework in existence).
CGI tends to be a crutch, and can easily ruin a good film if used incorrectly, with this movie being a perfect example. Even if it's only in the last ten minutes.
