I saw this movie. It wasn't bad, but it was a tad overrated. It's not something I can see myself rewatching, and it's definitely not my favorite Will Smith movie.
Its awesome! There are some sad parts here and there, but in that scenario, the character would have to be heartless to not have a few sad moments, especially since his wife, daughter, and dog were all killed. I dont think a grenade would have caused that kind of explosion in the end, though.
Grand opening was pushed back once again, we'll just say it's TBA for now. We are still waiting on the completion of some custom development that has been in the works.
