no, not really - the reasons:
(i) I have difficulty getting excited if Finland is not involved
(ii) the atmosphere is not all that great - this is because of how the ticket allocation works as there are not that many "real supporters" at games (of the games that I saw in France'98, only Japan-Croatia was ok thanks to the Japanese fans buying loads of black market tix)
(iii) world cup is a hassle, and an expensive one at that if you decide to go
(iv) you can drink beer when you watch games on tv

Besides, this is all theoretical as getting tickets to games is almost impossible these days.
