This is one for the hard core action fans. There's very little 'down time' to run for popcorn. If someone isn't getting shot, punched, etc. things are getting blown up or sunk in water. There is an action scene I haven't seen yet with a police car. Several of the action scenes are worth a rewind and I did appreciate the 'buff bodies'. You have to give these guys an A plus for working out.Chrissy K. McVay - Author

A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.
Positive

I have been very unhappy with this product because it:1) makes a high pitched buzz2) intermittently stops providing enough power causing my computer to constantly switch back and forth between battery and wall power.3) the cord is difficult to wrapI'll be trying to return it through the warranty process, but I wish I had just coughed up the [lots of] extra money to buy an Apple one.
