Really good special effects

I also have to agree. I was not expecting much and not only did they exceed expectations, I felt most (~70%) of it was done as realistically as possible.

Even in areas where the quality was a bit lower, I would say out of several tries, many of them were actually quite realistic and the rest broke the realism (namely: people getting stabbed by the spider's legs, some of the building debris falling and the spiders hatching). The weakest part was probably the webbing - especially when the female soldier got all rolled up.

Yeah agree with this comment... some effects were awful
