Greetings from Lithuania.
"The Vatican Tapes" (2015) is a very enjoyable "possession / exorcism" movie. While the plot is not really original, the ending kinda was original, really original. It has not bad mood for this kind of horror movie, and although it has clichés all around, the overall experience was positive.
Michael Peña is totally miscast in this movie, he is one of the most reliable "comic reliefs" in industry at the moment, so it is hard to take him seriously in priest robe with serious face, there were some scenes with him near the end when i just wanted to chuckle - not that he is a bad actor, he is solid one, but at this moment in his carrier this kind of movie is clearly not his strongest side. Djimon Hounsou is also a bit miscast, although this 2 times Oscar nominee is much more believable in this role. Others were OK, nothing special. Directing was also OK, and i kinda liked cinematography and editing, they create this feeling of uncertainty.
Overall, i kinda see why "The Vatican Tapes" has such a lot rating at IMDb (4.5 at the moment) - lots of recent horror movies about possession and exorcism are shoot in "found footage" style, but this one plays straight and its overall look is inconsistent, there are many close ups and shaky camera and some weird shoots, but as a whole i liked this style and as i have mentioned it creates this tension and feeling of uncertainty. Ending was also kinda original in my opinion. While this flick isn't the most original or best in its genre, it was a pretty descent one.
