I'm not sure how Plex could have been complicated. These are the steps:
1. Download and install the server. Literally less than five minutes.
2. Make sure your movies are named just like the movies are named in IMDB: "The Avengers (2012).m4v" for example.
#2 is the first totally unneeded complication. Every movie I own is named the way it makes sense to me and to the data gathering program I use. (Thumbgen)
3. Point plex to your movie directory or directories and let it download all of the meta data automatically.
Every movie I own already has an nfo file associated with it which contains all the "Meta" data for the movie. The file is named exactly the same as the movie file except for the extension. There is also a jpg so there is no reason for Plex to go out to the internet and download anything.
4. View your movies via PLEX apps on Roku, Android, IOS, browser, etc.
If you've wasted time downloading and/or creating your own metadata, it will also be picked up automatically as long as it matches the naming convention of the movie files. I really don't see any easier way any program could pick up local metadata.
The wasting of time is trying to use Plex. The arrangement and groupings that Plex forces just makes no sense and most of the time the info presented is totally wrong and the way the channel presents the movies is simply hideous. It also seems that Plex is much to tightly wound in its naming requirements as Thumbgen has absolutely no problem finding data for my movies (around 98% accuracy) exactly as they are named but Plex fails over half the time.
Plex wants everyone to use their local media in exactly the same way and that way makes no sense to me. As an example of how bad Plex is it insists the the "Lord of the Rings" movies are Science Fiction and they show up in that genera and the only way to fix it is to manually fix the downloaded data and that uses an interface that is almost impossible for me to get functioning or to tell how to do anything.
Under the good media players I use my movies are grouped exactly the way they are set in my directory structure and that is the way I want to see my movies. I do not want to see some other person's idea of the correct generas or the correct layout.
If Plex had a way to display exactly what I have already designed then II might use it as the actual server part seem pretty good but Plex will not do that.
Also, on time when I tested Plex would not use bif files to display thumbnails for FF, RW and pause. I don't know if that lack has been addressed but if not then that is another negative.
I suppose Plex might be OK for someone that is new to streaming local content but for those that already have a mature, stable and understandable structure it is just too complex. But, as I have said before, it is quite pretty but pretty is as pretty does and Plex does not do its job "pretty."
