I am a big fan of simple sites. I dont like sites with lots of garbage where you feel lost after a few clicks. Most of the movie ticket sites owned by the movie theater companies are totally crap. The one by PVR (I guess it is https://pvrcinemas.com) is the worst. These sites are so heavy, they take so much time to load and do break a lot of time.
I recently heard of BookMyShow and yesterday I booked an INOX, Bangalore ticket. This site is very light and user-friendly. I have become a fan of this site. The seat selection thing was cool yaar!
However, they do charge a service fee on every ticket, but that was a small amount. Anyways these movie theater companies also charge this kind of fee on their own websites, which I think is ridiculous.
Also, another drawback is that they do not have PVR in their list. PVR is quite a popular one I guess. Anyways, overall bookmyshow is a neat and simple site. Quite cool features which are useful too!
