Seriously they have thought about making more series out of it? LOL!
I seriously think that such kind of movies without reasoning is utter waste of time. Sometimes these shockingly have a good start or a good end though.
If you wanna watch some story out of box with very precise reasoning you should go for "The age of Adiline" If you haven't seen it yet. I saw a review about this movie and loved watching it after that.
By the way you can become pro reviewer on internet as you keep the readers stick to entire blog. Great job.
