This is the problem with today's society... people want everything and they want it right now, but don't want to have to do any work to get the result they want. There is not an FE that's going to download everything for you. Every FE is going to make you do some kind of work. Most FE's movies come from Emumovies unless you want to create your own videos.
You can't fault the guy for being spoiled by XBMC. It has everything that you would ever want, and does most of the work for you. If there was an FE that had that functionality, it would be the most popular one on the market, hands down. Don't take that as a sleight against HS (or Mala, or MA, or any other for that matter) because it's simply because of the integration of XBMC. You configure your settings, and it to look at three different XML based sites for media - it downloads posters and backdrops, media and series info for movies, TV and music. There simply isn't a backend to support that for the FE's that are out there.
Now, if one day, someone put together a website whereby the information was scrapable in XML format, and people could turn on their FE, watch as it scanned their ROM's for missing information, and then DL'd the game picture, game video, marquee, and scan of the cabinet - imagine what that world would look like.
The only question is - which FE will be first out of the box?
