Why...I ask WHY is it a four and a-half ton T-Rex from sixty-eight million years ago that undergoes the rigors of passing through a "Time Portal" (that ubiquitous script device overused to infinity and far far FAR beyond) can withstand modern weaponry? Ummmm... Elephants are KILLED all the time by morons wielding AK-47s in Africa and they weigh as much or more than a T-REX. Hello Sci Fi Channel, stop accepting movies written by Sushi Slurpin' Screenplay Writers who don't realize living flesh is just LIVING flesh. Thank you. Now, I'll just immolate myself ala Human Torch and woooosh off somewhere.
