Ah! I can give 15 reasons (if not 50) why a visit to cinema hall (in India) is a painful exercise. My worst experience was when no parking was available, I had to park on the road side and my Santro wipers were stolen.
Financial aspects too...
Going to a movie today typically is not cheap either. For a couple, ticket cost is at least 500 (250X2). Add some snacks, water...which are sold at high premiums in the multiplexes...add another 150-200 bucks. Commute...if in a car, petrol cost..considering the theater is 7-8 kms, you end up with petrol expenses as much as 100/-. Then parking at the mall..which can be anything between 30-50/- So, you spend at least 800-900 bucks just for 2 people. If there are more members (& unfortunately you pay for all), then this amount will increase exponentially.

No, I am not a grasping old miser but it's far more cheaper, convenient & relaxing to watch movie at home. Just like just4kix mentioned, you don't even have to worry about the treatment that your car would be getting at the parking, more so, if you love your car or you are a car enthusiast.
It's so much better to enjoy the snacks you prefer which can be other than chips & popcorn typically sold at malls & watch the movie.
You can watch late night shows at home without worrying about loved one's safety while returning to your home at un-humanly hours. More so, if you use public transport.
Although, my investment was not too high for HT, but still I think that I have recovered more than 2/3 of my investment watching movies at home. Should I mention that I got it set up just 4 months back in December?
