It sounds good regarding the death scenes, but I worry due to LucasArts being identified more with exploration here.
For me, it was the LA games that focused almost solely on puzzles, and the exploration posed no challenge at all. Often you just walked over to the next screen.
Sierra games had possibilities for very detailed exploration, and this is a big part of the appeal for me. Also, the emphasis on time constraints is not an important part of the Sierra magic in my book.
The very worst-case reading of this statement would be: little freedom of exploration, focus on puzzles and time constraints. Note that this is probably not the right reading!
