Sure, the movie has a lot of clichés, inaccuracies, common mistakes in destruction scenes (a suspension bridge's towers not bending outwards when the span is broken, for example), and a predictable plot, but these things go hand in hand with the disaster movie genre. If you expect those going in, then the movie is pretty entertaining. You're not supposed to take these films too seriously, you're just intended to go along with the ride of destruction--and what a ride it is! This movie has some excellent destruction scenes; although they aren't exactly realistic and don't always make sense, they're a lot of fun to watch, and that's the whole point.
Sure, if you compare this with all other films, it's not great; but in the disaster movie genre, with other such films as 2012, the Day After Tomorrow, and Greenland, it's actually pretty decent. Remember: the whole point of these movies is to show awesome scenes of destruction, and San Andreas does that beautifully, so don't take the movie too seriously and just go along with the ride.
