Not one of my SPEEDIER efforts for a Tuesday.
We have an odd theme today: three longer answers where the second part is a synonym for a horse-drawn vehicle. MARTINLANDAU, very good in Ed Wood. PAPERCARRIAGE is a term I'd not heard before, and in my exhaustively brief Google search I just did two seconds ago, I did not find it. Typewriters have carriages, but they're not referred to as paper carriages. This is a scientific fact. Then you have BATTINGCOACH, which is completely fine. Is it enough? Yeah, it's fine, just not anything amazing.
Despite that, I didn't really GROK this puzzle on the whole. DCON and NAZI sit shoulder by shoulder. ORATES is an unaesthetic word. EXO crosses EXPOSE. I never heard of Karen GRASSLE, although Hope immediately knew she was the mother on "Little House on the Prairie."
An uninspiring theme, and fill I didn't love. On a Tuesday.
