We Have a Ghost horror-comedy

 "We Have a Ghost." The movie seems to be a horror-comedy with a premise similar to "Casper" and "The Haunting of Hill House," with Anthony Mackie and David Harbour in supporting roles. The protagonist is played by Jahi Di’Allo Winston, who plays an angsty teenager named Kevin, tired of his family's constant fresh starts due to his father's missteps. When a friendly ghost named Ernest appears in the attic of their new home, Kevin finds companionship and emotional support in him, but his father sees a business opportunity and posts videos of Ernest on YouTube, attracting all sorts of oddballs to their property.

Your review suggests that the movie is overlong and disposable, and it doesn't use Jennifer Coolidge to her full potential. However, the premise of the movie seems interesting, and it might appeal to kids with short attention spans. Overall, you have given the movie a rating of 2.5 out of 5
