Yes watch Alias! For its problem areas, it's great.

For me personally... seasons 1 + 2 are great, as has been stated. If you watch anything watch them.

Season 3 isn't bad... just not as good. I'd still recommend watching it.

Season 4 is pants. Hard work, except for a few episodes towards the end of the season.

Season 5 is great, it's like old-style Alias again.

And because season 5 is great, I feel the show ended on a high. And season 3 is better after you've seen season 4, because you realise it's not *that* bad.
