Sam and Max: Seasons One and Two are fantastic point-and-click adventures that are quite true to the original entry into the series. It brings tons of humor and charm, as well as the interesting puzzles to back it up. However, GamePlasma wasn't too pleased with the visual revamping it's received, as they feel it's taken a turn for the worse.
Both seasons can be completed in a relatively short amount of time, which will leave you wanting a lot more than what you're given, but overall a very enjoyable purchase that will bring you back to the glory days of PC gaming. One can only hope that someday the Maniac Mansion series receives this treatment.
