Now that I've seen it however... let's just say that this "Final" movie doesn't do the manga justice. At all.
Assuming that you've seen all the prior seasons of Sora no Otoshimono before watching this, you should already know what to expect. It is the same good old character cast and the same good old perverted yet hilarious sketches. The only thing that really changes for real towards the end is of course the story.
The word "rushed" is not strong enough for this one. The pacing of Eternal My Master is a mess. It basically rushes through the remaining manga chapters like a runaway train, skipping a huge amount of content in-between, and while many of the key scenes are still adapted, the transition between them isn't executed well at all. As a result, the story just ends up needlessly hard to follow and the supposed emotional impact misses its mark.
Above all though, what really let me down was the ending itself. It just wasn't the same. Literally. The super emotional conclusion the manga had just didn't exist. Numerous key scenes from the very last chapters simply aren't there, and the epilogue is straight-up missing. Hell it hardly even properly explains why the ending it *does* have actually happens the way it does. Overall it just doesn't leave you feeling satisfied at all.
As a whole, the production value is still good and the girls are still as likable as ever, and really those are the only reasons I'm kind enough to give it a 4 overall. However the story is just incredibly poorly executed and as a result it will only leave you disappointed in the end.
TL;DR - Read the manga ending instead, pretend this one doesn't exist.
