OLD SCI-FI MOVIE ABOUT HUMANOID ROBOTS INVASION - WATER WEAKNESS

Unfortunately no. 

The movie was much more dark, it wasn't a comedy. 

@brainrotgrape​ OK. So maybe "Syngenor" (1990) ? According IMDB: "A woman finds her uncle lying on the ground with his face all cut up and bloody, she gets attacked by the Syngenor and throws a vase filled with water to the creature. Which causes damage to the Syngenor's body, smoke and light erupts from his chest. He bursts through a door while trying to attack the woman, she uses a small homemade flamethrower to burn it's face. The Syngenor screams."

No, but I'm pretty sure that the movie Im looking for is from the similar period of time, because of the water weakness motive. 

Something between 1975 and 1990. 

It can be also a tv series, I'm not sure. 

And maybe "Alien Nation" (1988) ?

User classicsoncall from IMDB wrote: "I remember how fascinated I was with the concepts explored in this picture back in the day - the idea of curdled milk as refreshing, and sea water corrosive to an alien race."

No :( 

But I really appreciate ur effort.

Scenes I can remeber took place at night. The stadium scene also.

There was some woman character I think which turned out to be a robot.
