[EX Q]: Michael Bay movies are meant to be action packed fun cheesy goodness. Which this is. The reason I'm giving this a bad review is because Amazon Instant Prime has edited out parts!! It's a PG13 movie!!!!!! It doesn't need edits! Considering how much we pay a year for Prime, I expect to be able to watch the full movie.
[EX A]: Negative

[EX Q]: I used this program for my science class. My students loved it! They learned some interesting facts, saw damage from earthquakes we talked about in class and never once did I hear that it was boring! Can't beat that!
[EX A]: Positive

[EX Q]: You get what you pay for. I have used these batteries as back up for the original Canon one. After 10 months with only occasional use, battery won''t take or hold a charge. Do you self a favor, and buy a Canon battery. You'll save money in the long run.
[EX A]:
Negative
