You can get most DVDs for 6-7 quid, equivalent of renting it 3~ times from a rental store, if it's a film you're likely to watch more than that over a long period of time, you may aswell buy it.
I personally buy DVDs of films that I know are good, and rarely buy something without seeing it beforehand at some point.
Generally I buy movies that I'm pretty certain I'm going to like; and most of the time I'm spot on, even when I haven't seen the movie before. There're've been a few bad choices - I bought Garfield, which I really regret doing. I mean, it was fun, but it's not a DVD I'd own, with hindsight.
So honestly I don't think buying DVD's is a waste of time, unless of course you buy them, watch them once and then never touch them again. People who do that annoy me, because it kinda defeats the point of buying it.
I buy DVDs if I can't find them for rent, or if I completely love the movie.
But, I can't decide right now if I want to buy one...I liked the movie, but its slightly too long, so I don't know how often I'd be inclined to watch it.
I'm buying my mom "March of the Penguins," and for how long a movie it is, it is really expensive.
I tend to buy TV series DVDs then movies. I don't have a very long attention span. (Erg, New Who is another rip off, for how many episodes it is, it's 33% more than Lost, which has 9 more episodes..)
i thought this thread was gonna be about HD-DVD/Blue Ray...
Anyway, I would say most people buy dvd's for their own personal collection, a collection of films they already enjoy. Fanatics may buy stuff they've never seen (e.g anime, film buffs etc) but i dont think most people do this.
About 75% of the dvds i own i bought after id seen them before but others i just buy from word of mouth or because my friends are too straight laced and wont go and see them at the cinema with me! But there are occasions when i think oh that looks good or i buy them for a course, if they turn out awful i can sell them on Ebay/Amazon so its fine.
ive just bought the pride and prejudice dvd for £7 from hmv and i know i wanted to buy it cos my mum had borrowed it from her friend. so if i can, from now on, i'll be borrowing then buying. i think my mums friend had seen it at the cinema so thats how she will have known she liked it
I usually only buy DVDs if I'm pretty certain I'll actually like them. But most of the time, I buy them used and cheap anyway, so I can always just sell them on Ebay if they really are completely rubbish.
I usually rent them if I haven't seen them (how can you argue with 3 for £5 at Blockbuster?).
Someone previously mentioned HD-DVD and Blu-Ray technology. It is for these reasons that I have now stopped buying DVD's and will currently only rent.
I see it as another case similar to that of replacing VHS with DVD so I've decided instead to wait for either of the two aforementioned technologies to come to the masses. I've no idea which one will win the battle.
I own about 70 DVD's which have seen substantial use so I'm happy with what I've got out of them. I've certainly got value for money anyway.
To answer the thread question directly, no I don't think buying them is a waste of time but the advice I've listened to is to wait for the next development. I think that then it'll be fairly safe to buy again. Of course, I'll inevitably replace many of the films in my collection.
Like one of your examples though, I wouldn't generally buy a DVD in the past unless I'd seen it first or knew it to have a good reputation. I have also occasionally bought a DVD through recommendation.
Well, I usually buy dvds if a movie is recommended by a friend, or if it sounds like I'll like the plot from reading reviews etc. I have been dissapointed once or twice but if you get peoples opinions then it should normally be alright.
