This is the worst movie i ever watched in my life!

At last i can say it with confidence, and i think i will watch (but who knows what species 5 will bring to us?).
Nothing interesting in this movie, no plot, everything is predictable and what is not predictable is simply a plot hole, i mean the whole story revolves about an alien who doesn't know what she is really, and yet she is like 28 years old, seriously?! the characters behavior is just strange, at some moment someone going to kill you then ally with you for no reason then try to kill again, also for no reason! it was a mess !
Now talking about acting, actors, and this stuff, the dialog was simply ridiculus, i am not sure if it was their fault, but i felt like returning 15 years in the past when we were trying to act on stage, i was even better, as i remember.
Now the "special effects", this is what matters in sci-fi movies , and it is true, who cares about a plot, when someone can evade a bullet! that's just cool and i'll watch a movie for it. however in this, at least, let's say there is nothing "special" about the effects, they relied on the plot :)
