El guardián invisible

Any confusion, and unsolved ends, are due mostly to this movie being part of a trilogy. Two movies are available now, and I think the third is soon to be released. The concerns over the tarot cards, and the mother etc. are all made clear in the second movie. I almost feel as if this would've been better as an entire series because if you only watch this first movie you'll miss out on the WHY of it all. I like the way it all eventually falls Into place, but this isn't obvious unless you watch both movies.
