Anticlimactic is often used to refer to a disappointing ending to an exciting series of events. So, (not being a native speaker) I cannot decide whether it sounds natural to use the word at the start of an event.
Say some exciting events happen that lead to the beginning of something or maybe some epiphany causes you to resolve to go through a painful transformation. But then for some reason the start itself is the opposite of thrilling.
In that case, does it feel natural to read:
After the anticlimactic beginning, however, ...
or is some other word more suitable?
