I'm getting really annoyed with the player on the FX site.
You sign in through your cable provider, and then it automatically starts the first episode on the list. Sometimes, you click 'Watch Episode' for a different episode, and some late sign in action trigger re-defaults it to the first episode on the list.
The episodes are, of course, in reverse order, so this causes me to catch glimpses of the 'Previously' scenes from the season finale. Which contains spoilers.
It's bad enough on HBO Go where you have to scroll through the full list of episodes in reverse chronological order to select each individual episode you want. At least it doesn't automatically start episodes later in the series than you currently are. Why is it so hard for these sites to have a cookie-driven season view?
Also FX currently has an ad for their series 'The Strain' which has a worm crawling out of somebody's eyeball, right next to the viewer, limiting the size of the viewer to much less than the size of the screen, and the only way to get it out of your field of view is to either full-screen it which you might not want to do at the moment or actually move half the browser window off the edge of your monitor.
On a related note, Fargo is getting progressively more awesome at the same rate it's getting progressively less plausible. I still don't get why they committed to the same 'Fake true story' format of the movie if they were going to approach it like any other fictional series.
