I watched it to see how far they would go. To be honest, no one can be that bad by accident, whether acting, script, dialog, whatever. Not by accident: it has to be intentional and one has to work hard at it. So abysmal that it made me laugh on occasion.
I guess it is interest in this attempt at breaking barriers and setting new records of outrageousness that won the participation of actors we have seen in better context.
Spoiler (though spoiling this movie is hardly possible): Another good thing about this movie is that all the characters get killed: they all deserve it.
Given that the film was actually trying to be bad, I must consider it a real success. I must logically rate it at 9. I actually hesitated between 9 and 10, but I want to encourage them or other filmmakers to try even harder to see whether they can do even worse. I actually read from other reviews that Asylum can do worse. So my guess is that 9 is the right rating.
Still, I give this movie 2 stars because it made me laugh. Here are two approximate excerpts from the dialog, from memory :
Son: "dad, there is a report that says this is the end of the world." - Dad: "it is much worse than you think."
Agent: "The earth stopped rotating. The sun won't set". - Reply: "do not tell anyone."
Apparently, I saw only the second half on TV. Lucky me. I could not really watch it continuously (kind of painful, even though I can swallow a lot of stuff when it comes to SciFi), so I watched a rather interesting documentary on dinosaurs at the same time. They had clearly more emotions than the characters in this film.
Just one question : if an asteroid breaks, what are the chances that two pieces will fall on the same spot. Close to zero. What are the chances more than two will ... Now, given that the planet rotates quite rapidly, what are the chances that several will fall on the same spot at different times. This is just one example of the utter technical nonsense of the thing (then ... what is to be expected with the kind of pseudo-science taught in too many schools). But the rest (acting, dialog, scenario, ...) is on the same level.
I would give it a 1, but I still give it a 2 on the odd chance that there might be something in the first part I did not see.
