Since one decade, the theory of gravitational microlensing entered into the reality and some experimental groups like EROS and MACHOS started to observe dozen of microlensing candidates towards Large Magellanic Cloud (LMC). The interpretation of these events in the framework of galactic models is the matter of debate. In this article we summarize the results of experiments and the statistical analysis and show that the known galactic models are not able to fit with the microlensing data. The conclusion could be either correction on the galactic models or the microlensing events might be due to the background. Using the parallax and finite size effects for breaking degeneracy between the lens parameters in the Next Generation Microlensing Experiments will certainly resolve this problem.
