I totally agree.
1972 - David: 'I was gonna scare you. Were you scared?' 1972 - Vicki: 'Terrified beyond belief.' And just look at the smile on his face and then hers:
And because of all that I wish we had seen more of Vicki and David interacting with each other, particularly when it came to matters of the supernatural in general and his mother in particular (but more on the latter after the slideshow has reached that part of the scene). Just more material introduced in this scene that could easily be a part of that whole other film.
