CGI isn't the greatest for most of the effects, but the spiders themselves were pretty well done. It gets interesting quick and stays rather interesting throughout. There's a lot of movie references, I don't think I caught them all, but some are more obvious than others. It's mildly humorous with a couple good scares and creeps, lots of action. Loved the nod to Spiders 3. It may not be a movie I watch more than once, but I enjoyed it all the same and look forward to watching the second one.
