A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies
