These horror films should be about 80 mins. otherwise there is a problem maintaining the suspense. This one also needed to reign in the violence as its excess became a turn off.
Pegg is a good choice but the material does get a bit repetitive. However the animated characters breathe a bit of life into events when things start to lag.
There is acting talent to burn here plus there is Tom Cruise. There was a chance to kill him off in the first scene but the talented Bernard Hill paid the price instead. Excellent production values.
The Orca segments (literally) looked authentic. I found nothing wrong with Orca sticking its nose into other people's business (boats) and was a good way of getting the message across to those bastards that hunt whales.
