I love a good ghost story. I practically worship a great ghost story. Sadly, Altar is neither. It has its moments, and it's not a complete waste of time to watch, but in my opinion it started with all the makings of a truly interesting story and mixed it all up into a batch of...mixed up.
The true star of the film is its Yorkshire manor location. Now, if I'd been handed this set to work with (and if I, you know, actually made movies), Altar is NOT the story I'd have come up with. I actually felt a bit annoyed at the movie for not living up to such a classic haunted house setting! The premise was simple enough, and it started out in fairly contemporary spooky fashion, but there was just not the right kind of follow through. Rather than spine tingles and after-view thoughts about mortality, the climax delivered only a mash-up of effects and incoherent, half-explored themes.
I will say this: the actors who played the children did great. Williams did fine in her role, and even Modine did the best he could with what he was given (his character was the biggest mess in the mix, with some truly uncomfortable scenes - and not in a horror/mystery sort of way).
Generally, you could do a lot worse for your hour and a half, but if you want a great haunted house / ghost story, look elsewhere. It's been done a thousand times better at least hundreds of times already.
