Class survey conclusion

As a class, we decided that American producers can afford to create better, and more action films than English producers, because they more sponsors and more money. However, when discussing it with the class, we came to the conclusion that more English movies are serious, and historical, whereas American one are more varied. We found out that most of the class preferred a comedy or a horror movie, than they would a documentary, or sci-fi.
We also discussed the pros and cons of watching movies in different ways, for example, going the cinema, watching a DVD, downloading the movie or watching it on TV.
The pros of going to the cinema to watch a movie are being one of the first of many to see a new film, there's surround sound system, its dark, and the screen is huge. The cons of going the cinema are things like it not being quiet all the time, for example, the crackling of a bag of food, the crunching, annoying laughs at funny parts, babies crying over the sound, there being no seats and having to split up with the group that you went with, it being claustrophobic, and being in a packed room, it's also expensive.
The pros of watching it on DVD are things like you can watch it more than once, and whenever you like, it can cheaper, they're portable, you can lend it out to others, you can watch special features of the movie and you can pause and play it whenever you like. The cons of watching it on DVD are things like its easily damaged, or lost, it could be a pirate copy, or might not work properly, the viewing experience wouldn't be as good as watching it in the cinema, you could lose interest in it.
The pros of watching it on TV are things like, the excitement of watching it on TV, and not having to look for the DVD, not having to pack away the disks after the movie finishes, it's doesn't cost much, being able to see a film you might of been able to seen beforehand. The cons of watching it on TV, is you have to wait for a certain time to watch it, you get breaks during the movie, they miss out parts at the breaks, you can't pause it whenever you like, the interesting movies are on later which means you have to stay up late, you don't get to choose what's shown.
The pros of downloading a movie is, once you've downloaded a movie, you can watch it any time, there's a huge variety of choice, you can watch it anytime, you're in control of the film, e.g. pause, play, fast forward, rewind. If it's on a laptop, it can be portable, you can burn it onto a disk, or put it one your iPod. The cons of downloading a movie is that it's illegal, takes a while to download, you can download a virus, might have to pay to download it, might download the wrong language, could get caught downloading it, you could delete it accidentally.
We found that there are many different ways of marketing like bill boards, posters, radio adverts, TV adverts (trailers), newspaper and magazine adverts, bus advertising, pop up ads on websites and word of mouth.
We said that trailers are the most effective way of marketing, because if the movies new, you get an idea of what the movie is about, however if it's a known movie that's coming out, and they have a big fan base, then the trailers will be shared more often, which means more and more people would watch it, and it'd be bigger than it was.
