    Maybe not. We have a lot of smaller galaxies near us. And Andromeda is bigger than we are.

    Here’s a thought for you. The Andromeda Galaxy is barely visible to the naked eye. On a good night in a location with no lights, you can see a kind of dim, fuzzy area. Even with a small telescope, it looks pretty much the same, dim and fuzzy (ie no details stand out).

    When it is half of it’s current distance, everything should be four times as bright (inverse square law). However, the area subtended in the sky will also be four times as large. So it more or less remains a dim, fuzzy thing, for a quite a while. Eventually, beings would resolve features, and it will look impressive. The nucleus should stand out pretty well as it comes toward us, but it will be a while before it appears brighter than what we see as the Milky Way.
