Found this old summary while thinking about the subject of artwork, linked to the proliferation of videos in meetings these days. The same points FadeToBlack made apply - the videos are often used as over-simplified indicators of what you should think/take away from the item.
What I find crazy is when some comments gush about the artwork (including videos, dramas) illustrating Bible scenes from long ago, as if it were real footage from the past. I remember one brother even said when commenting on such a picture in a WT article: "As we can see in the photograph..." I'm not sure if that was a slip of the tongue and he just meant 'picture', or if he really does consider these artist's impressions (or video director's imaginings) as if they were direct recordings of events!
I've never found the artwork that impressive on a 'teaching' level. Sure, it may be (mostly) well drawn/painted, but there are thousands of good artists out there capable of illustrating all kinds of imagined scenes - that doesn't make the WT artists' (or directors') take on Bible accounts the 'gospel' truth, if you'll pardon the pun. Especially when it comes to things like Bible character's hair or clothing colours, or what poses they were in, or how many were in a room, things which are usually total speculation as there is rarely that level of detail in Bible accounts.
Study article should be highlighted in multiple colors.
With the near-ubiquity of tablets and mobile phones at meetings now, at least the days of showing off how studious you were by having your publications highlighted in lots of colours have died out. Although some do carry over their highlighting obsession into the JW app on their devices, it doesn't seem to be such a mark of 'spirituality' as it used to be. At least that's one ridiculous thing that has gone away!
