3D Cinema / Virtual reality

The world of today has changed a lot and now we are getting 3D films which makes the film come to life. This is only good with some things for example I went and watched 'How To Train Your Dragon'  which i enjoyed so i went onto the internet to see what other people thought about the worst 3D film ever and it came up with 'The Jonas Brothers 3D Concert' which people were saying was not a good one to watch in 3D as it still did not feel like you were at the concert as there was nothing that looked like there was going to be a lot of objects or anything that was going to fly towards you. But people where saying that the best film in 3D was 'pirana 3D' as it felt like the piranha was going to go after people in the cinema as they felt like they were at risk.
  Positives

• Makes unrealistic situations seem realistic as if you are in the place it was set.
• Easy for people to enjoy.
• Makes you feel like you are in the place that it set for example if you are watching a darts match in 3D it looks like the darts are coming at you.

Negatives

• They are trying to make it 3D without glasses which could cause a lot of people issues for example the Nintendo 3Ds is glasses free and people are finding it really hard to watch it and not get a headache from it.

In my opinion I think there is only one  main negative and for that i believe that 3D films should keep them as they are good. But they should be kept with the 3D glasses as I have been at a film where they had it with no glasses and I struggled that afternoon as I had a headache from the film that I had watched.
