I would agree. If you wanted to play MP then not having it working can be quite frustrating.
Eventually it will all be fixed but as a whole, it's a very good collection. Having all maps from each game for MP is a feat. As well, considering it's a collection, it does an extremely good job in creating excitement from the franchise.
It made me interested in Halo 5. I never really liked the series but after playing the first 3, it's funny that an older franchise like Halo could feel fresh and new because it's almost completely opposite than the current FPS franchises.
Maybe Valve is smart in releasing Half Life 3 (if ever released) so it hits the market when it's saturated with "follow me marker" CoD clones.
