I almost didn't see this film, buy my wife was late getting to the theatre, so we caught this one. I'm glad I did, because I liked it. Perhaps it was because the theatre was very loud, The ending was a little different with the ghost staying with one of the main characters right up until the end.
Sure, a bit of a ripoff, but I liked the pace and the different camera shots.
Quite a few articles to choose from regarding FOX's cancellation of Terra Nova, but The AV Club's (avclub.com) was the funniest. There's talk of shopping the show around to other networks, but good luck.
