I remember years ago watching the first and extremely-hyped Harry Potter movie and being thoroughly disappointed. The plot seemed irrelevant, and the action involved some broomsticks and special effects that looked like something from the early 1980s. Based on what I remember the film would be firmly in my Tier 1, likely toward the lower end.
Does the Harry potter series get any better? (read: Way, way better than the first film by an enormous margin) I've been told that the first films are lousy because they are pitched to a much younger audience, and that later in the series the plot gets much better (read: much darker) and the characters far more complex.
I personally like fantasy films to be visually exquisite in the landscapes and special effects (Lord of the Rings), to have consequential plots with memorable characters (not some imaginary land for bratty children in a wardrobe with a lion and an ice witch and some garden gnomes) and to maintain a level of dramatic intensity that is utterly immersive for the viewer (again, Lord of the Rings). I like when it's unclear whether main characters will actually survive a given conflict or obstacle. If the film has the tone of "well it's a children's movie so of course none of the main characters will die no matter how bad the predicament" then I lose interest since any struggle or conflict seems a waste of time given that viewers can already guess the outcome of the scene and likely the entire story.
To this point I've simply ignored the Harry Potter series based on my experience with the first film. However I'm now thinking about the fact that Star Wars Episode I was horrible, but then was followed up with much better films in episodes II and III. I'm generally willing to endure bad starts to a series if I know there is a worthwhile payoff later on. Is that the case with Harry Potter? Is it common for people to strongly dislike the first film but really like the later ones?
For most films I find Criticker PSIs do a good job but I find for intensely hyped films (e.g. Star Wars films, Coen Brothers films, Quentin Tarantino films) the PSI is useless for me.
