Netflix streaming selection is still inferior to its DVD selection, however; it is still better than either of the other unlimited streaming options. Amazon Prime's main selling point is free shipping on all Amazon orders of any cost, so the streamign is just an additional benefit, but they do have a respectable selection of BBC and PBS content. Hulu Plus's selection is downright dismal if your viewing preferences are anywhere close to mine
If you don't mind gettign stuff on a per rental deal, Amazon and Blockbuster offer streaming pay per view (with stuff not availablle on Prime) for about 2.99 to 4.99 depending on how recent the title is, but you have a narrow window to watch it in. Even tho I only watch a couple new movies a month, I don't like the narrow time window, so its just not an option that works for me. Some of the new relases can be purchased on Amazon for as low as 9.99 which is a more tempting option. The other thing I don't like about any streamed content is that they are not yet including the director comentary tracks and other bonus feature, but Netflix is also starting to move to stripped down DVDs that omit those features too.
Blockbuster has a decent selection of TV shows (not quite as complete as Netflix), and a slightly better selection of movies - some movies like Suckerpunch are available sooner on Blockbuster than Netflix. Blockbuster does not diferentiate between normal DVD and Blu-ray pricing, so if you don't have a Blu-ray player (which I do not), then Netflix is stilll cheaper for DVDs, but that savings has the cost of waiting longer for new releases. For those with Blu-Ray, I would recomend Blockbuster if you watch more movies than TV shows. If you don't have Blu-ray, you can still go with Blockbuster to send a message to Netflix, but you won't actually be saving any money. It is also worth noting that Blockbuster also has video games as part of their rental package - if I had a 360 or PS3, that would probably be a deciding factor for me.
My current plan is to try to make more use of the streamign while I have it and then eliminate streaming when the price change kicks in. I'll loose streaming, but they will be gettign less money from me in total. If netflix or a competitor starts offering newer titles (that I actually want to see) on streaming, then I may switch again
