A lot of observations were put off due to the "sticky" motion controls for MIRI. Also keep in mind that because JWST is not a visible light instrument, many of its observations may not be sexy enough for mainstream press. The kind of observations for which it is best suited are just a lot of data that must be computationally analyzed to make sense of it.

But hey, nearly all the raw data is available for download, so if you want pretty pictures, all you have to do is learn to perceive streams of IR data.
