I really hated that dance scene in the movies ugh. It's cute yes, but is not at all close to what actually happened. Plus it's so against Guts' nature. That scene is vomit inducing.
But aside from that, in my experience with the TV series, it's worked well for me to get people into Berserk. I find it holds up a lot better than the movies for the story. It's a lot easier to get people to just sit down and enjoy it and then move them onto the manga if they feel like reading it.
But without a season 2, most people just won't be bothered continuing with the story. It's unfortunate but in my experience it's just not happening. But to one of my ex-girlfriends credit, she did read the series two and a half times in less than a month after she seen the TV eclipse. This was a person who had every excuse to not read it (despite being completely her type of thing).
The movies have made it far easier to get people into it though. The short duration of the first movie makes it easier to get people to jump into the second. Then the WTFness of the trailer for the third movie make people want to see the third ASAP.
I've had pretty much everybody I've ever known since these came out to watch these. It's been a 100% success rate with people loving them and wanting to see more. But I also felt obligated to take the time to explain shit that the movies couldn't have been bothered with. Which has also been 100% appreciated because they admittedly wouldn't have understood a damn thing if I didn't explain anything. Which I hate the movies for but it's necessary.
But again, very few move onto reading the manga. Only another one of my ex-girlfriends, my current roommate and one of my friends classmates have read the manga itself because of the movies. The rest are waiting for the new TV series.
As for myself, it was the original TV series back in around 2001 that pulled me into the series. I was around 15 or 16 then and I was hooked from the start. I watched it all in one sitting completely addicted.
The eclipse then proceeded to fuck up the rest of my day and I became one of the people who were waiting for season 2 to come around. Not because I didn't want to read but the books weren't out in Canada yet. Years later, the books were published and I've been hooked since.
Sadly the fact is, despite probably getting about 10-12 people to read the series, I am literally the only one to buy any form of it. I think one of my friends will probably some day, but I'm the only one. This is despite Berserk having a 100% success rate with every person I've shown any form of it to (manga, TV or movies). If it wasn't my books they were reading, it was scans online. The variety of reasons are that people prefer to just pirate, total laziness, the books being unavailable to buy, lack of funds, 37 books being daunting etc etc.
So, is the new Berserk anime doing more bad than good? In my experience, absolutely not when it comes to creating interest or new fans. Has it helped sales though? Hell no, not from what I've seen. At all.
But as a whole, they've at least created an interest for a lot of people from a quite a few different age groups from both genders. I have not met a single person who didn't end up at least enjoying it and most come away with a genuine love for it.
