Parts. I'm going to skip the usual fare and mention the heart-shaped gem, along with the four different varieties of 1x1 round Tile. There's also the minfig camera and the Minifig Roller Skates for interesting pieces.
Build. A quick Station.
The Questions:Can you build something -- a frame, station, or starship -- right away? Yes. (+5)
Is it below, at, or above the golden ratio? Below. (+5 ) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? No. (-5)
Score: +10 (A-). Not a bad score for a Friends polybag. A handful of pieces more and it would have made the max score.
