Speaking of the makeup, there are a few scenes where the makeup looks really good...mostly the outdoor night shots. Then there are scenes, and perhaps this is a pitfall of high definition, where you can see the dry crackling & flaking that comes with theatrical creams applied directly onto skin. This is mostly noticeable on the cheeks and around the eyes & lips.
It seems, that along with the unsteady flow of this film, there was a bizarre effort (conscious or unconscious) to overshadow character development with levity. Each time a character would demonstrate any significant depth of emotion it was either accompanied with, or quickly followed up by a bad comedic moment.
Three significant "for instances" (which may be lightly spoilery):
When Barney's spilling his guts to Liz, we get the organ fiasco overwhelming the sentiment of the moment. When Barn & Vicki are sharing their one and only brief intimate moment, we have the 70's Scope commercial gag. When David is devastated by a set of consecutive painful realizations, we immediately shift focus to the fire/water stunt.
While the subsequent trailers concentrated on the comedic highlights, the very first trailer showed the proper balance of this film. About 1/3 (or so) of the trailer is serious, dark & straight forward and the remainder is what it is. This holds true for the movie as well. The writer himself (SGS) is on the record stating that that particular trailer is a very fair representation of what the film actually is. He is 100% spot on.
