unbrilliant

adj

1. Not brilliant.

   “Walderhurst, who had been much bored by himself and other people in time past, actually found that it gave a fillip to existence to look on at a woman who, having been one of the hardest worked of the genteel labouring classes, was adapting herself to the role of marchioness by the simplest of processes, and making a very nice figure at it too, in her entirely unbrilliant way.”

   “And some are apparently so unbrilliant that they go directly to DVD (which, with films of this genre, is really some kind of achievement)— e.g., Road Trip: Beer Pong, a 2009 movie about which Drinkology would prefer to know nothing.”
