Rise of the Tomb Raider - The ending thoughts

When I finished Rise of the Tomb Raider, there was an underwhelming sense of disappointment. In the back of my head, I could tell something was off.

It was during the climax that I noticed it retreaded the ending of Tomb Raider (2013) too closely. From the snow covered environments to the linear pathway full of enemies. The only divergent change it had was the ending boss--Konstantin with a helicopter.

I know the old analogy "If it's not broken, don't fix it", but it should have made an effort to be different, especially near the end.
