No spoilers here.
Last night, I had the opportunity to run a pickup game of LotFP for some lovely folks on G+. I had been itching for a chance to run +Jason Sholtis's little micro-module, Zogorion: Lord of the Hippogriffs, and decided this was the perfect chance.
The Good: Brevity! This micro-module can be read in about 15-20 minutes. That's really all the prep you need, unless you want to add some more customized hooks, or reskin something.
Jason injected just enough character and personality into Zog, the main NPC, to make him a fantastically interesting character, but left a lot of the little details up to the Referee to nit pick or hand wave.
This is in no way a railroady module. You can lay the hook(s) and see how the players take them. The location described is openly laid out in the module so that a Referee can allow the players to approach the challenge however they wish. Within there are even several major items that could be drawing factors or goals for PCs besides the obvious interactions with Zog.
The Bad: I honestly can't say much about it that isn't good. Maybe the fact that he hasn't written another like this yet?
I suppose there are a few little details left out regarding Zog's lair. They are easily filled in by a good Referee, of course, so it's not a real problem. I can't lay out the details here without spoilers, so I'll leave it at that.
The Ugly: Nothing. Seriously, I can't find anything that I just scoffed at. This was easy to read, easy to tweak and tailor, and a blast to run.
Where can you acquire such a delightful module, you ask? Why at Jason's blog, of course: http://roll1d12.blogspot.com/
