We praised great BO performances to high heavens, so naturally we also poke fun at BO bombs and underachievers. Don’t see anything wrong with it.
JL was a laughing stock for a while, and Solo failed even more spectacularly than JL, so some ribbing is warranted. And the movie hasn’t been out for a week in US yet, the horse is still alive (barely, but alive, so it’s ok, it can take more beatings)
