All new voice acting
There's like six voice actors, and they're probably just buddies from the pub. I would actually argue that the original voices were far better.
music, sounds
The only fantastic part.
and models
High quality? Yeah. But they cut out significant portions of the original game. I don't think the model quality justifies the butchering of certain areas of the levels.
all by a team of 10ish people.
A similar sized team is making/made No Man's Sky. A far smaller team made the original concept for Portal. Counter-Strike and Team Fortress were both original mods works on by one or two people.
I personally don't think the price is justified. Unlike Stanley Parable where they added content, Black Mesa just renovates the existing content with shiny graphics and new audio, but in order to do it they had to chop out parts of the game. Furthermore, multiplayer Half-Life has existed for years; both in the form of Deathmatch AND in the popular mod "Synergy". Hell, I think even Garry's Mod is capable of loading Half-Life 1 maps for multiplayer.
Not for me, thanks.
NOTE: I'm not even considering Xen. Given how long it took them to get Black Mesa finished (which has a lot of resusable assets), it doesn't necessarily bother me.
