My 2 year old son talks to a point?

He says car and points to the tv(meaning he wants to watch the movie, or he gets the movie and brings it to us and says car) we ask him if he wants to watch cars he says yeah. He does say dada and mama and nana. He does calls his friend Key(her name is Kenzie) He does ask questions like what is that or who is that. He can say hi and bye. He can try and say bird. He can also say mine and what oh and no nite nite...and just no. he can say all this stuff but its not very enunciated. Should I be worried or am I overreacting???
