I think you have to also remember (may be wrong here) that unless you are using a proxy ip then you can be caught by your ISP for downloading illegal copyright content by the film chaps etc
I use netflix and its a £5 a month and apart from the new stuff there is heaps on it and its legal
PirateBay and other such things (torrents) also have problems that the downloads are 50/50 complete with hacks and viruses
Your ISP won't have any interest in policing your downloading habits. If you're direct downloading material then there's no chance of getting caught but if you're using a bittorrent based download such as torrents then you ipaddress will be visible to others in same swarm which means your ipaddress can get harvested and you'll receive the naughty boy letters. The letters come from the copyright holders or their agents but are forwarded by the ISP's in the UK because there's a legal requirement for them to do so.
There are ways to hide your ipaddress when using torrents but it can get a bit messy and it will cost money for a VPN, the bittorrent protocol was never designed to be anonymous, by its nature it requires ipaddresses are resolved during the process of transferring the file.
If you're using torrents you need to keep up to date with what's happening because of the cat and mouse game that constantly goes on. For a start get some news from one of the mainstream sites
like torrentfreak, you can subscribe to their daily news emails. EZTV for example had their
website hijacked recently by opportunists but funnily enough, The Pirate Bay that you mentioned specifically is pretty clean if you stick to the uploaders who have a good reputation, you can spot the idiots and the fakes a mile away if you know what you're looking for. If you're a regular bittorrent user you should make the effort and join a couple of the private torrent sites which are far better moderated and their content is squeaky clean.
One of the most prolific piracy issues at the moment is
Popcorn Time. It's similar to Netflix on the front-end but in the background it uses bittorrent to stream the movies. As ever, the reason it's so popular is because of the insistence of the movie industry to try to hang on to the old style restrictive business models which include staggered global release dates, geo-blocking, region coding and opportunistic/inconsistant pricing structures etc etc plus Popcorn Time also usually offers better quality HD than Netflix does and the catalogue of movies available is far larger. Using Popcorn Time in the UK would be risky without a VPN because, as I mentioned, it uses the bittorrent protocol.
