....what's your point....?
1. it's a for profit business marketing a 'product' that impacts on people's beliefs about life meaning......it therefore is not immune from being analysed critically like any investment or product.
2. the OP asked for views and expressed concerns about it being cult like in effect. I've read a fair whack of the literature Landmark state the course is based on, and watched several people go through the program. I still see several of these people years later.
Others have talked of how Landmark has been a positive experience for them.....Here's the story of two I know well.
-------------------------------------
I've known X for 8 years. She attended Landmark in 2007 hoping to improve her small business and family relationships. I knew her issues well, and suggested before she did Landmark she might alternatively consider spending the money on a specialist accountant, lawyer, and business consultant specializing in her industry, in the view of elucidating her business's potential. It was obvious to me the business would not improve its revenue or profit, or reduce manhour requirements.
X didn't have the free cash flow that justified risking ~$500 on an investment in Landmark. She has 3 kids, one with special needs, and another with behavioral issues. Her husband was at serious risk of being made redundant and his health was suffering due to high stress at work.
Landmark staff convinced her the course could only help improve her business and family dynamics. I felt this was unjustified as they had little to no insight into either. X did the course and was immediately an enthusiastic convert, so much so that she convinced me to go along to an info night, where I spoke at length with two of the staff. X had been identified by Landmark staff as an asset, and was fast tracked into the marketing machine, and follow up courses. For around 12 mths she was investing time and energy in marketing the course to others, including several staff in one of the clinics I worked at.
To cut a long story short, family issues worsened, and were compounded by X running herself into the ground after investing another 15k and 60 hours a week into the business. Her health issues escalated (takeaway meals for the family, very unhealthy weight gain by X and her children, X required thyroid medication). The youngest still had special needs that were going unmet due to financial lack.
As a health professional and friend of both her and her GP, my view on her life issues was more privileged than the Landmark staff concerned themselves with. Nevertheless, X was desperate to hold to the 'glass half full and soon to be overflowing' mindset...and she would grasp at anything that propped that up. X's GP and I felt Landmark exacerbated in X an irrational and unconstructive approach to her issues.
In my view, in addition to X spending her money on the above business professionals, she would have been better investing that time and money with a highly trained and experienced psychologist who cared enough to become familiar with X's life and mindset.....and more skillfully and effectively help X re-prioritize and deal effectively with her issues.

I've known Y since the mid 90s. X recruited him into a Landmark course soon after she did hers. Lots of people think he hasn't tapped his full potential. Handsome 30 something single guy, smart, sensitive, personable, though stuck in a middle management job that seems to leave him a little flat and easily tired. He did the course, found it interesting, and the group dynamic effect was to encourage him to get more out of life, aim higher, take some risks, etc etc. Several months later, Y had some issues with his balance which he saw me for. I did some tests and wrote a letter to his GP. A brain scan revealed a non malignant tumor putting pressure on surrounding nerve tracts.
Y's case demonstrates that often there are legitimate physiological signals people get from their bodies, that inhibit them from more actively pursuing what others' value.
