Hmm, well I think the edited together 'films' are crap - the joining sequences don't work at all, and cutting old Indy removes alot of the magic and context for the episodes. He frequently gave the stories modern paralells, so the audiences could see things haven't really changed all that much.
Alot of the dramatic weight of the series lay in the old mans reminiscing, highlighting say, the irony and futility in the Verdun episode - Indy may have destroyed the orders to attack, but he could only save 10,000 men for one day longer. Very poignant and tragic stuff.
I think part of the reason alot of people dislike the series is its 'European flavour'. The films always felt 'American' - the series was quite different in feel. This and, y'know - the show actually wanted to teach you something and didn't have Indy pistol whipping people every 5 seconds.
Unless you've got the attention span and brain capacity of a waterbiscuit, I fail to see how you could find the series 'boring'.
So my favourites?
London, 1916 - Wow. 45 of the best minutes of television I've ever seen - the chemistry between Indy and Vicky is completely believable and moving,
Liz Hurleys best ever performance too (though she is only playing herself). Stunning Holst inspired music, a beautiful study of the sexism of the time (with many modern parallels), and fantastic performances all around.
Curse of the Jackal - the whole damn telemovie, exciting, exotic, wonderful television. Tell me that slow zoom in on the Jackal at the end doesn't give you chills and I'll eat my fedora.
Verdun, 1916 - just watched this one again yesterday, stunning McNeely score, very powerful episode. Makes war appear less of a game than the Somme episodes did.
They're probably my top 3. Austria and Russia 1917 are both excellent too, many great episodes.
