it wasn't for me since barney becomes an established character in half-life 2 and the character in barney's mind doesn't come across as the same person.
one thing i'd like to mention though is that making a mind series is a lot more work than i expected and i appreciate anyone who does it as long as they aren't saying exceptionally cringe things. barney's mind didn't come across like that, i just got the sense that barney was kind of stupid. i didn't watch the entire series so i don't know if it got any better as time went on, but it just wasn't hooking me.
got through barney's mind, i actually ended up liking it more than shephard's mind. most of the dead air in barney's mind is filled unlike notable instances in shephard's mind where there's no dialogue from shephard, and like shephard's mind not every joke landed but there were some good lines here and there.
