I have gotten it to work through BlueStacks. Unfortunately, once a video started playing it would have a green box around it. I did choose internal player.
To install through Bluestacks I had to install Chrome, then download the app, it wasn't as smooth of a process as it sounds.
I was pretty unsatisfied then and was going to write more negative things but I decided to at least try the Chromecast option. Installed the same way, through Chrome, but on my actual phone this time, and I also installed LocalCast. (I think my new favorite CC app) I was a bit skeptical about it actually working with Chromecast but when you deselect internal player you can choose LocalCast as an option and just click the Chromecast button in the corner. I haven't noticed any green lines and the quality looked slightly improved. But Bluestacks could have had an issue with my PC's resolution.
After more testing I will say that Netflix clearly will provide better quality for the same show or movie, these films appear to be coming from a database similar to torrents but it does make it simple and the interface is straightforward. Sadly you'll be faced with some ad "mini games" (really just ads) you'll have to press the 'X' in the corner and it will immediately go away allowing you to continue. Could be worse, you could actually have to wait or make a difficult decision on which x is going to make this ad go away.
I was thinking your original goal was to waste my time when I was first testing with BS. That would have been a nice turn of events.
In comparison to Popcorn Time I do prefer Showbox, while I don't face ads with Popcorn Time I've noticed films unavailable there and the speed of Showbox through my Android has actually been quite fast. I don't think Showbox is better with quality or chooses the best video file to play but I feel most of these type of applications and services have these faults. Popcorn Time has continuously played some incorrect episodes, along with Netflix getting them out of order.
Thanks
@blankrider, you have introduced me to two great apps I feel I would have not found quick enough.
