Don't be guided by the onimnously scary title of this 3D film. Into The Deep is a documentary, not a horror and you'll be dissapointed if you expected an adrenaline rush.

However, if you were wanting a nice relaxing 40 minutes of the movie equivalent of going scuba diving - then you'll have a great time.

My first and only word of warning is:

BOOK EARLY AND CHOOSE YOUR SEATS!

I've been to the IMAX before and had great seats (about 2/3rds back and slightly off centre), but this time we were running late and ended up right at the front. The screen is absolutely huge - the entire height of the building. Sat at the front, you not only get major neck ache from staring straight up, but the 3D effects are almost entirely wasted.

You need to be a certain distance away for your eyes to manage that 3D thing. If you take off your special glasses during the film, you can see that the image is made by having at least two images of everything. Your eyes are tricked into converting this into 3D messages. But, if you really are too close, it doesn't quite work! It is too much of a gap between the duplicate images and your eyes struggle to make sense of it. I found that the film seemed out of focus and the 3D bits just blurred more.

After ten minutes we abandoned ship and crept up the centre stairs to sit on them at the top.

This was a much better view and everything seemed sharp. The only drawback was the two handrails, either side of us that were constantly in view!

It actually adds to the 3D effect by being far enough back to see the fish swimming over the audience and obviously it seems more impressive if things jump out of the screen right at you, if they've got further to go!

If you've been following the Blue Planet series, this film can't compete on subject matter, but that is more than made up by the feeling that you really are in the water. Weed floats by your fac
e now and then and you have to stop yourself from brushing it to the side (you'll look a fool!)

The shark is the most impressive 3D fellow but the whole idea of gliding through hundreds of tiny fish is just as captivating.

At £7.00 a ticket, half an hour arrival makes all the difference in the quality of the experience.

If you are a nature lover, this is a must.
