Nope, no broad strokes at all. Everyone is entitled to their opinion so that we can all understand each other a little better. Also, it's not a binary discussion of "I hate the PT" or "I love the PT" it's a discussion of reasons why people have the opinion they do. I personally enjoy hearing both sides of the equation and can empathize more as I understand more.
I enjoy the way some of these threads are headlined with "hate" and then like clockwork everyone breathlessly scrambles to say "well..uh, uh, I don't hate it...." I don't hate 'em either. But I did find them long, over elaborate and the actors are miscast, and the acting is detached. It's the classic case of trying to fit in too many a-listers, they all wind up ill-fittingly cast. Now I haven't seen these films in years. Maybe they'd grow on me if I saw them again. But I'm not that motivated to revisit them though.
Seeing Rogue One at the cinema really has re-invigorated my interest in the franchise, that's what compelled me to do a marathon watch the other Saturday. The hype for TFA got me more interested sure, but I enjoyed RO so much more in comparison, that I felt the need to revisit the stories again having not watched them in maybe five years plus.
People just love to hate things. Some people prattle on endlessly about how bad Ghostbusters II is when they: a) haven't seen it since 1989 or b) haven't seen it at all!!
But why the extremes? OP was looking for the reasons people don't like the PT to articulate them, not broad strokes of the whole of Star Wars fandom.
Don't hate them at all. In fact, I like the more epic scope compared to the original trilogy. Lucas' dialogue and direction is atrocious but there are good spots. The "B" story in AOTC involving Obi-Wan's bounty hunter mystery and where it leads him could be a good film all by itself.
Which is why AOTC rates so highly for me. I wonder if TPM would have been more interesting if Obi-Wan had been on his own.
SOME people hate the Prequels; a vastly larger majority of people (both die-hard Star Wars fans and casual moviegoers) do not.
Jar Jar was the only entertaining part of that self-important, stick-up-its-ass series. The writing was one long trudge to give people origins that really didn't give any insight to anyone in 'A New Hope', It made Jedi like Yoda and Kenobi seem unbelievably dull-witted and short-sighted to not see what a lunatic Anakin was. The adult Anakin would have been more believable played by an actual piece of wood. In short, the idiotic muppet was the only thing remotely entertaining in a series that made Star Trek Nemesis seem like an enthralling character study of Shakespearean proportions.
At this point, using Jar Jar as an excuse to bash on the Prequels is an illegitimate argument and the people who continue to rely on it have no credibility.
That is similar to my view. The Jedi, the good guys, come out as looking incredibly short-sighted and ignorant of what's going on.
^ Because the Jedi's losses in the Prequel Trilogy directly set up the Rebellion 's victory later, yes.
