The Message isn't a translation. It's a loose paraphrase by someone who paraphrased the whole Bible. It's not a translation by a group of people who are experts in Hebrew, Greek, and Aramaic. People need to have more respect for God's word and use an actual translation like the classic NIV.

It's thought that the Gospel of Mark was told from Peter's point of view. It's also thought that it was the first gospel written because over 90% of Mark is found in Matthew and/or Luke.

There's some controversy with the ending of Mark. As it says in wikipedia:

Mark 16 is the final chapter of the Gospel of Mark in the New Testament of the Christian Bible. It begins with the discovery of the empty tomb by Mary Magdalene, and Mary the mother of James, and Salome. There they encounter a young man dressed in white who announces the Resurrection of Jesus (16:1-6). The two oldest manuscripts of Mark 16 (from the 300s) then conclude with verse 8, which ends with the women fleeing from the empty tomb, and saying "nothing to anyone, because they were too frightened."[1]

Textual critics have identified two distinct alternative endings: the "Longer Ending" (vv. 9-20) and the "Shorter Ending" or "lost ending",[2] which appear together in six Greek manuscripts, and in dozens of Ethiopic copies. Modern versions of the New Testament generally include the Longer Ending.

There's a long article about the endings.
