Yeah I find American exaggeration (over-positivity) quite tiring. Good things become "amazing" and "literally the best ever". Even "great" is just around median in actual meaning. Everyone is "excited" to meet you and "thrilled" about whatever you say, wide smiles etc. Complaining about anything is a huge no-no, your life narrative must always be carefully crafted and anything slightly negative rephrased as a positive challenge and learning opportunity. Everyone is a hero sitting on a great exponential upward curve ahead of them. You are considered negative and a downer for just not buzzing all the time. Seems like people care even more about "saving face" than in East Asia.
