I'm pretty bummed how he was conveniently cut out of the movie after the crash on Jakku. He would have had a perfect role to play in their escape and him being around would have effectively avoided some of the pitfalls of the film.
Yeah, this is one of my major gripes of the movie. Instead of spending that whole sequence on an awkward and bad monster CGI sequence. They could have give Finn and Rey some time alone. Maybe stop into another star port. Somehow get flagged and Solo finds them.
