Stein's gate

Should I watch it? I've seen some AMV's of it and seems cool but I don't want to end up with wasting time over it. And is there a bad or good ending? (Don't spoil it with saying what it is, just say if it's good or bad.)

I loved this anime, but I have to admit I think the first three episodes are kind of bores as it's still introducing things, but if you invest your time into it I think you'll like it. I know I did

One of the best anime of 2011, with one the most most unexpected twists. This anime starts off pretty slow but as @Empire said it gets really good half way through the series. No but seriously there is so many twists in this anime that when you go on the character page on "Myanimelist" and click on the spoiler tab there is 2 pages of spoilers, compared to other anime with like 4 lines of spoilers and the twists are really unexpected and add to the plot, unlike other anime which just add it for the scare factor.
