Good start, but then it gets ruined

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.
