My wife and I both enjoyed it. It's a set-up episode. Shows some action, shows some fun, gives you a rough sense for where they could go.
Pretty much all of the Berlantiverse shows have had somewhat shaky starts, but later turned into really good shows. I thought the Supergirl pilot episode was kinda weak, too, but now that we're some 7-8 episodes in, I really enjoy it. I expect the same will happen here, although I can't help but question just where they'll take some of the characters (especially Heat Wave). Dom Purcell has only done a few of these episodes, and while he's fun to watch, his character gets kinda dull after a while. But then, because they haven't given him much of a chance to develop, I think that's understandable. Anyway, I guess we'll see, but on the whole, I'm pretty optimistic.
And I dig Rip Hunter as being a cross between Malcom Reynolds and a Time Lord, and the ship being half TARDIS, half SSV Normandy.
