SC2 is a lot of fun. It's very memorable and still probably my favorite out of the whole series. Not to mention link was pretty fun. Actually one of my favorite parts about this game is the voice acting/quotes.
I wish people would be a bit more open minded and actually give 5 a chance though. The actual gameplay is excellent and possibly the best in the entire series. It's possible it won't have your favorite character(It didn't have mine), you'll also have to adjust to some new mechanics, and character movesets always change between these games. But if you go into it judging it as a new game by its own merits and not by how it doesn't have talim, you might end up really liking it like I did. The game was rushed though, there's no denying that. It's clear that with the short time they had, they prioritized balanced gameplay and very good online modes over more story/modes/characters. (A choice I agree with, but others may not)
