They rate very heavily. The games themselves are very fun and very different to many games we see these days. Every 'episode' has its own plot that contributes to the overarching story arc without ever making you feel like you've not accomplished something and there are some extremely funny moments in the games.
I'd highly recommend the series to anyone.
Difference in opinion is not an attack, merely an opening to discuss different perspectives and views. Play a game then judge, don't judge before you play.
I loved Hit the Road as well and wish they would give it the special edition treatment like Monkey Island 1&2. Am finding Devils Play House the best of the new ones so far but saying this I have still not played Season 1 of the new games and am waiting for a cheap copy to turn up which I just ordered on the Wii (don't have Xbox360 or gaming PC access)
