How is this in the top250 again? Scratch that. How is this above a 6/10?

Rating: 1/10 (21 May 2015)

Did we all see the same movie? See the same question that everyone asks, so it becomes a cliché, exactly what this movie was. This was a cliché on top of a cliché parading on a freaking mountain of clichés.
If anyone would be kind enough to explain what makes this an 8/10 I would be happy, it wasn't even THAT entertaining if we only take into account the enjoyment factor alone. One note characters with no chemistry or interesting group dynamics, flat and boring interactions combined with a dialog filled with one liners that weren't even funny. Cartoonish villains and all too generic and familiar plot,like in any other superhero movie ever, made this sh*t as predictable as it could be. Hell even the action and the overall execution of the storyline was textbook presentation.
How did this bland,unoriginal,uncreative,uninspiring and too formulaic cash grabber managed to get in the 250 best movies ever? 8.1? 6/10 would be fairer and closer to the truth as the action might pass as entertainment. Personally for me it's a 4/10,I was actually bored by it as I expected something amazing.
