I agree it should have executed better, but I'm a little more forgiving. Probably because I am exactly who this was aimed at. I still had my Intellivision until a couple of years ago, and set out gathering up several of my favorites. I do wish there were more though. Only a fraction of my old games are available, and I keep seeing games on the promo screen that never became available (1000s of games *scoff*). My 11-year-old self would be ashamed of how far my ability at some of these has fallen.
What I wish XBLA would have done is present all of my downloaded arcade games in this format, so Assault Heroes and Castle Crashers would be in there too. Make interacting with my downloads a little more visually appealing. Beats all the other useless crap they've choked my Live menus with.
