Yeah, here’s a great video ( < 4 minutes) about it.
The night sky before it and during the collision will be spectacular, but after it all settles, it will be pretty bland!

What is really interesting and confusing to me is that these interactions are of course gravity based. But gravitational influences travel at the speed of light, and these beasts, like our own Milky Way galaxy, are 100,000+ light years across! So surely there has to be an enormous delay factor of sorts. Even the neat spiral structure of a given galaxy is very mysterious to me because of this. Our Milky Way is a spiral galaxy roughly 100,000 light years across.
