I am not a fan of handheld ghost hunter type fictional television episodes in general, and Haven Season 4 Episode 11 felt like a lot of wasted filler to get through to about 10 minutes of worthwhile content.
Coming off a strong, information-packed episode like we had with Haven Season 4 Episode 10, that was a bit disheartening. After all, we struggled through the first handful of episodes of this season with a lot of filler with Audrey/Lexie behind a bar due to circumstances beyond her control, so we have some making up to do.
But, it is what it is. I'm not going to waste any time talking about the visitors, because they didn't serve a purpose.
