overall i liked the movie considering some i have seen on the sci-fi channel i found this believable if dimension traveling was actually possible. what i didn't like was the ending an i don't know if this is an actual spoiler but i think we should have seen whatever they saw an not left us hanging. the actors were good, though it amazed me that it too so long for them to realize they were leaking freon. though i don't agree with the other reviewer i don't think the creature is similar to predators more like some kind of spider with those multiple eyes an it runs like a kangaroo holding the front legs forward to give it speed. overall as i said the movie was good an my seven year old granddaughter liked it also it was not so scary she asked me to turn it off.
