None of the above. Alita was best among those I watched.
Second best, hum, hard choice. I guess I enjoyed Avengers Endgame more than Toy Story 4, Parasite, and Joker.
My ratings for the relatively few 2019 movies I already watched:
1) Alita: Battle Angel - 9.5/10 (Excellent cyberpunk action despite its numerous flaws as it shove too much plot into too little time)
2) Avengers Endgame - 8.5/10 (Really polished blockbuster movie, nothing wrong with it although a bit plain it did exactly what it tried to do so it was almost flawless IMO)
3) Parasyte - 8/10 (Nice, entertaining movie overall)
4) Joker - 8/10 (gave 9.5/10 earlier but on a more sober evaluation it was a good movie but not a truly great movie)
5) Toy Story 4 - 8/10 (a really well-made movie)
6) Wandering Earth - 6.5/10 (rather an average movie, nice to see, however, how a major Chinese science fiction blockbuster looks like)
7) Captain Marvel - 6/10 (the definition of an average blockbuster movie)
8) Terminator Dark Fate - 6/10 Best of these "new" terminator movies, still quite mediocre
9) Maleficent: Mistress of Evil - 5.5/10 (super mediocre stuff)
10) Rise of Skywalker - 5/10 (really bland crappy film, probably the worst major Star Wars movie ever made)
11) Pokemon Detective Pikachu - 4.5/10 (meh)
12) Bacurau - 4/10 (one of the first Brazilian science fiction movies, its basically a Marxist version of Road Warrior, suffers a lot from its heavy-handed ideology)
13) The Irishman - 3.5/10 (a boring outdated movie that consists of genre self-parody, the people who made this should retire)
Overall, from the few movies I watched, it was a good year.
