“Unwelcome” (*1/2 out of four) was an unwieldy horror melodrama about a married couple (Hannah John Kamen and Douglas Booth) who decide to start a new life for themselves in Ireland but soon meet a nefarious neighbor (Colm Meaney) and discover malevolent and murderous goblins lurking in the mist. Meandering and plodding story takes a long while to get off the ground and even when it does- it’s pretty feeble and formulaic and then goes on too long. Meaney is solid as usual but he can play a role like this in his sleep by now.
