Hey sarinsarin it's LG WRman Greg here!
Your friend gave you a good advice, you should definitely get a passive 3D TV. Passive 3D gives you a great experience, close to the one you get in the movie theater. In fact, LG has a line of TVs called cinema 3D that is mind-blowing. On top of the passive 3D technology that allows you to watch 3D movies with light, comfortable and above all flicker-free glasses, you get an almost frameless TV which helps the viewer focus more on the image itself. This brings you the closest 3D home experience to the cinema that you can get. In fact, LG has been awarded with a 2012 Edison Award in the ""content display"" category. The smart TV will bring you also an almost infinite content with great applications like facebook, twitter or skype. My advice to you would be the LM8600 which is the top of the cinema 3D line.
If you have any more questions feel free to ask or check out the official site for more info at LG Electronics India: TVs, Mobile Phones & Appliances.
LG WRman Greg out!
